2026-04-22Electrical insulating tape
Electrical insulation tape is the most fundamental and critical material in the field of electrical engineering. Its core function is to isolate current, prevent short circuits and leakage, and provide certain mechanical protection. It may seem simple, but tapes made of different materials and structures have significant differences in temperature resistance, pressure resistance, and flexibility. Choosing the wrong tape may leave safety hazards.📋 Types and Comparison of Mainstream Electrical Insulation TapeAccording to the different substrates, electrical insulation tape can be divided into the following categories, and you can quickly screen according to your own needs:Substrate type represents product examples, core characteristics and temperature resistance levels, typical application scenarios, key performance parametersSoft PVC tape Desha 53988, 3M Super 33+universal type, most commonly used. Good elasticity, comfortable hand feel, flame retardant, available in multiple colors for easy identification. The temperature resistance level is usually 80-105 ℃. Insulation wrapping, joint treatment, phase identification, and daily maintenance of wires and cables. Breakdown voltage:~7kVTensile strength:~25 N/cmPolyester film tape Intertape 51588, SynTape ® PM.099 is thin and strong. Thin thickness but high dielectric strength, tear resistance, and solvent resistance. The temperature resistance level is usually 130 ℃ (Class B). The interlayer insulation of transformer and motor coils requires precision windings with small space occupation, as well as scenarios that require immersion resistant paint. Breakdown voltage: 5 kVTensile strength: 40-44 N/cmPolyimide tape (Golden Finger tape) Su Rui Electric's high-temperature resistant tape is the king of high-temperature resistance. Ultra thin, resistant to high and low temperatures, and resistant to acid and alkali solvents. The temperature resistance level can reach up to 180 ℃ (H level) or even 260 ℃. Insulation protection in high temperature environments, such as lithium battery lug fixation, SMT welding shielding, and high temperature coil wrapping. Long term temperature resistance: 260 ℃Excellent chemical resistance🔍 Interpretation of Key Performance IndicatorsWhen selecting, one should not only look at the name, but also pay attention to these core parameters that determine quality:Voltage endurance/breakdown voltage: This is the most critical insulation indicator. High quality PVC tape can usually reach 6-7 kV or above. For high-voltage scenarios, it is essential to choose products that have undergone withstand voltage testing.Temperature resistance level: directly determines the service life of the tape. Use letters to indicate the maximum temperature for continuous operation: Class A (105 ℃), Class B (130 ℃), Class F (155 ℃), Class H (180 ℃). Motors and transformers must have at least Class B or higher internal components.Adhesive type:Rubber: It has strong initial adhesion and easy bonding, but is sensitive to oil and chemical solvents. Suitable for regular bandaging.Acrylic acid: high temperature resistance, aging resistance, and good chemical resistance, making it the preferred choice for oil resistant tapes for equipment such as anic silicon: has the highest temperature resistance level (above H level), and there is no residual adhesive when peeled off. Suitable for extremely high temperatures or situations that require clean chanical strength: including tensile strength and elongation. In scenarios where bundling and fixation are required (such as the end of a motor coil), the adhesive tape needs to have sufficient tensile strength (e.g.>30 N/cm) and ductility to ensure that the long-term bundling does not loosen.💡 Combining your previous needs (transformer scenario)Based on your previous question about "transformer oil resistant tape", the selection process will be clearer:If it is interlayer insulation for transformer coils, what you need is polyester film tape (such as Intertape 51588) or glass cloth tape. They not only have a temperature resistance of B level or above (130 ℃+), but more importantly, acrylic or cured rubber adhesives can resist long-term immersion in transformer oil, and the thin design does not affect heat dissipation.If it is external wiring terminal wrapping: a universal high-quality PVC tape (such as 3M Super 33+or Desha 53988) is sufficient. It has good flexibility and can tightly fit various shapes of connectors, providing reliable insulation and mechanical protection.If it is insulation for high current busbars (copper bars): thicker heavy-duty PVC tape (such as 3M Super 88, thickness 0.22mm) or professional self-adhesive silicone rubber tape is required, which can provide stronger wear resistance and insulation thickness.⚠️ Important NoticeAll industrial grade electrical insulation tapes should comply with the corresponding international or national standards. When selecting, you can pay attention to whether the product has passed certifications such as IEC 60454, UL 510, or VDE, which are the basic guarantees of its performance and reliability.High temperature resistant glass fiber cloth pressure sensitive adhesive tape
This is an industrial tape with excellent performance, combining the mechanical strength of glass fiber cloth with the temperature resistance of special pressure-sensitive adhesive. Here are its core components and key features, which I have compiled into a table for you to quickly understand:Typical parameters and key values of characteristic dimensionsImported high-density alkali free glass fiber cloth provides extremely high tensile strength (up to 420-600 N/25mm), wear resistance, and dimensional stability, and is not easily anic silicone pressure-sensitive adhesive (mainstream) or acrylic pressure-sensitive adhesive is the key to high temperature resistance, allowing it to work for a long time at 200 ℃ and even withstand extreme temperatures of 260 ℃ to 288 ℃ for a short period of time.The core features include H-grade insulation (with the highest heat resistance), flame retardancy, solvent resistance, and no residual adhesive.

This performance enables it to work stably in extreme environments such as ovens, high-temperature spray lines, or inside motors.Extremely high mechanical strength: The glass fiber cloth substrate endows the tape with astonishing tensile strength, making it very suitable for scenarios that require secure bundling or use under high stress, such as wrapping and fixing coils.Excellent electrical insulation performance: This type of tape usually meets the H-level insulation standard and has a certain voltage resistance ability (such as 3kV), which can be effectively used for insulation protection of electrical equipment such as transformers and motors.Clean removal characteristics: High quality silicone pressure-sensitive adhesive can still be cleanly peeled off from the adhered surface after high-temperature treatment, leaving almost no residue. This is crucial for processes that require temporary masking, such as high-temperature sandblasting and baking paint.Typical application scenariosWith the above characteristics, this tape is widely used in:Electronics and Electrical Industry: Used for H-grade heat-resistant insulation binding, such as insulation of dry-type transformer leads, packaging and fixing of motor coils, insulation wrapping of lithium batteries, etc.High temperature manufacturing process: As a high-temperature masking tape, it is used for wave soldering protection, high-temperature sandblasting protection, ceramic component fixation, and other scenarios on printed circuit boards (PCBs).Industrial and special fields: Used for wire harness winding, high-temperature pipeline sealing, and strengthening insulation and mechanical protection in heavy load environments in industries such as aerospace, automotive manufacturing, and military.How to choose?When choosing a specific product, you can pay attention to the following key points:Confirm temperature resistance level: Confirm whether your process environment temperature remains stable within a certain range for a long time or only has short-term high temperature. Silicone tape usually has higher temperature resistance.Clear adhesive system: The mainstream choice is silicone pressure-sensitive adhesive because it has higher temperature resistance and does not leave any residue. If the temperature resistance requirement is not high (such as below 130 ℃), there are also lower cost acrylic adhesive systems to choose from.Reference benchmark models: Many high-quality domestic products can completely replace internationally renowned brands in terms of performance, such as 3M's 69 #, 361 #, or TESA's 4618 #.

It is recommended to request samples from multiple suppliers for comparison.Seeking customization: Most factories accept customization. Products with different light transmittance, customized color codes, anti-static treatment, or special widths and lengths can be requestedGlass thinning and etching protection UV anti-adhesive PO protective film
In glass thinning and etching processes, a special protective film is required to protect non processed areas. UV reducing film (also known as UV film) is designed for this purpose, and PO (polyolefin) is one of the high-performance substrates.It is like an "intelligent shield" that firmly adheres to provide protection during processing. After processing, it can be easily and completely peeled off by UV light irradiation without leaving any residue.⚙️ Core feature: How does it work?The excellent performance of UV reducing film in glass etching process is attributed to its unique design:UV debonding and non-destructive peeling: this is its core function. Before exposure to ultraviolet (UV) light, the tape has high adhesion (such as initial adhesion of PO material up to 1300 gf/25mm), which can firmly adhere to the glass surface and prevent etching solution from penetrating. After completing the protection task, the adhesion will instantly decrease significantly through UV light irradiation, reaching a nearly non stick state (such as PO material dropping to 25 gf/25mm after debonding), making it easy and non-destructive to peel off, effectively avoiding the risk of glass substrate cracking due to uneven tearing force.Excellent acid and alkali corrosion resistance: Highly corrosive solutions such as hydrofluoric acid (HF) and hydrochloric acid (HCL) are often used in etching processes. This type of protective film can effectively resist the erosion of these chemicals, preventing them from warping, peeling, or seeping during complex acid washing processes.No residual glue, high cleanliness: Excellent UV debonding process and colloidal formula ensure that after the film material is peeled off, the glass surface can maintain its original cleanliness without adhesive residue. This is the key to ensuring the quality of subsequent processes and product yield, and it is also an important reason why PO protective films are highly favored in high-end applications.🛡️ PO substrate vs. PET substrate: how to choose?The performance of UV thinning film is closely related to the substrate (i.e. the main material of the film), and the common ones are PO and PET (polyester film), which have significant performance emphasis in glass thinning etching process. You can choose according to your specific application scenario:Characteristics PO (Polyolefin) PET (Polyester)Base material characteristics: The material is soft, with excellent ductility and cushioning properties. The material is relatively hard, with good stiffness, better temperature resistance, and dimensional stabilityThe key process is manifested in glass thinning/etching, which can provide excellent adhesion and buffering protection; Excellent acid resistance performance, some products can be sprayed under mixed acid for more than 200 minutes without acid leakage or detachment. They perform well in cutting, grinding and other processes that require high fixation force, with good processing performance and easy punching and cuttingThe application scenarios are mainly recommended for complex chemical etching, glass thinning, and strengthening processes. Its excellent acid resistance and flexibility make it the preferred choice for single-sided thinning of mobile phone glass covers, OLED/TFT panels, and other fields, mainly used for high-strength cutting, grinding, and other processes. It is also suitable for glass thinning protection, but in terms of acid resistance, conventional PET film may not be as good as PO filmViscosity change (gf/25mm) approximately 1300-1600 before UV irradiationAbout 25-30 after UV irradiation and about 1100-2200 before UV irradiationAbout 6-7 after UV irradiationReference temperature resistance: Long term temperature resistance of about 80 ℃Short term temperature resistance can reach 90-120 ℃, and long-term temperature resistance is about 80 ℃Short term temperature resistance of about 120 ℃Adhesive force (gf/25mm) refers to the adhesive force on a width of 25mm, with higher values indicating stronger initial adhesion.🔍 Application process: from attachment to peelingUnderstanding how it operates in actual production helps to better understand its value:Attachment: Before etching, apply the UV reducing film evenly to the glass surface that needs to be protected (such as the display area), and ensure that the two are tightly adhered without bubbles.Etching: Chemical etching is performed, during which the protective film, with its high viscosity and acid resistance, effectively blocks the etching solution from corroding non target areas.UV irradiation: After etching is completed, use UV curing equipment to irradiate the protective film. The photoinitiator in the adhesive layer reacts rapidly under UV light irradiation, causing cross-linking or changes in the molecular structure of the adhesive layer, resulting in a significant decrease in viscosity.Peel off: After UV irradiation, the protective film with extremely low viscosity can be easily and completely peeled off from the glass surface without leaving any residue, completing the protective missionHigh temperature textured paper tape leaves no marks
1、 The principle behind 'leaving no trace'The key to achieving "no marks" on high-temperature textured paper tape lies in its synergistic effects in materials, environment, and operation:Adhesive formula: High quality products often use silicone or acrylic pressure-sensitive adhesives, which have good thermal stability and can maintain cohesion even at high temperatures, avoiding softening and infiltration into surface micro gaps.Substrate characteristics: The fine striped structure on the substrate of the masking paper reduces the ineffective contact between the colloid and the surface, ensuring that the adhesive layer falls off as a whole without leaving any traces during peeling.Environmental factors: High temperature, high humidity, or ultraviolet radiation can accelerate adhesive aging and increase the risk of residual adhesive.Attachment duration: The longer the adhesive tape is attached, the tighter the bonding between the adhesive and the surface, and the higher the risk of residual adhesive.It is usually recommended to remove the adhesive within 24 hours after attachment, as the risk of residual adhesive will significantly increase after 48 hours2、 How to use it more perfectly✅ Correct usage methodCleaning the surface: Before pasting, ensure that the working surface is clean, dry, free of oil and dust, which is the first step to ensure the pasting effect and avoid residue.Press in place: After sticking it on, use fingertips or a scraper to fully press it, ensuring that the tape is tightly attached to the surface without leaving any bubbles.Timely Tear off: After completing the work, tear off smoothly at a 180 degree angle and low speed as soon as possible to minimize adhesive residue.Try before sticking: Before using it extensively on important or sensitive surfaces (such as genuine leather or high-end paint), be sure to select a small and inconspicuous area for testing.❌ Beware of Misunderstandings in UseExcessive temperature: Tape has a clear working temperature range, and exceeding it may cause carbonization or residue. Please make sure to choose according to the product instructions.Forced fixation: Meiwen paper is mainly used for masking and temporary fixation, and is not suitable for carrying heavy objects or withstanding huge tensile forces.Long term retention: The design intention of masking tape is for "temporary use", and long-term retention will affect its performance.3、 What should I do if I encounter residual glue?Even if high-quality products are used, improper operation may still result in slight adhesive residue. You can try the following safe cleaning methods:Gentle cleaning: Dip a soft cloth in warm water and soap solution, gently and repeatedly wipe. This is the safest method for the surface.Alcohol wiping: Dip a soft cloth in a small amount of 75% medical grade alcohol and gently wipe the residue. Alcohol is relatively safe for most surfaces and is a common choice.Wind oil essence/hand cream: You can apply wind oil essence or hand cream on residual glue, and the oil components in it can help dissolve glue marks.Eraser: For residual glue on rough surfaces, you can try repeatedly wiping with a regular drawing eraser and removing it through physical friction.Professional cleaning agent: If the above methods are ineffective, a specialized adhesive remover on the market can be used, but it must be tested in an inconspicuous small area first to ensure that it will not damage the surface.Bright black (matte black) polyester film
Bright black (matte black) polyester film is a common functional PET film in industry, characterized by excellent light shielding and mechanical and electrical insulation properties. The choice of two surfaces mainly depends on the different requirements of the application scenario for light parison of core featuresCharacteristics: Bright black polyester film, matte black polyester filmMain features: The surface is bright and smooth, with strong reflectivity, visually more eye-catching.

PTFE tape is indeed a fairly mature industrial solution for the challenges you encounter in demolding, workpiece scratches, and high-temperature environments during die-casting processes.It essentially combines the non stick properties of polytetrafluoroethylene (PTFE) with the convenience of adhesive tape, forming a smooth and high-temperature resistant "physical barrier" directly on the surface of the mold.🔑 Core Performance: Why is it capable?The reason why it is suitable for die-casting demolding mainly depends on the following performance:Excellent high temperature resistance: This is a basic requirement. High quality PTFE tape can be continuously used in the temperature range of -70 ℃ to+260 ℃, and some products can withstand high temperatures of up to 300 ℃ in the short term, which can stably cope with the high heat environment during the die-casting process.Smooth and extremely low friction coefficient: Its surface is very smooth and almost does not adhere to any substances (such as molten plastic, resin, etc.), ensuring smooth demolding of castings and effectively avoiding scratches.Excellent mechanical strength and durability:Scratch resistant: Teflon itself has a certain degree of hardness and wear resistance, but the mechanical strength of the tape depends more on its substrate.For die-casting scenarios, it is recommended to choose reinforced adhesive tape based on glass fiber (commonly known as "fiberglass cloth base"), which has high tensile strength and can better resist the impact of molten metal flow and the wear of mold closure, thereby achieving reusability and reducing maintenance costs.Widely resistant to chemical corrosion: It is almost not corroded by any strong acid, strong alkali, or organic solvent, and can adapt to various release agents or oil stains that may exist in the die-casting environment.Cleanliness and residue free: After high-quality silicone pressure-sensitive adhesive is peeled off at high temperatures, the back of the tape will not leave stubborn residue on the surface of the mold being bonded, which helps to keep the mold clean.High insulation performance: Teflon tape also has excellent electrical insulation performance, with some models having a breakdown voltage of up to 25KV, providing additional protection in scenarios that require electrical isolationSelection and usage suggestionsTo select the most suitable adhesive tape for your die-casting process, you can focus on the following aspects:Clear usage requirementsTemperature and pressure: Confirm the working temperature and pressure that the mold is subjected to.Wear resistance requirements: Based on the mold structure and working conditions, evaluate the requirements for the wear resistance of the tape, and decide whether to choose pure PTFE film (with good flexibility, suitable for complex surfaces) or fiberglass cloth based reinforced type (with high strength and more wear resistance).Thickness and size: Select the appropriate thickness (such as 0.08mm, 0.13mm, 0.25mm, etc.) based on the precision requirements of the mold, and confirm whether a specific width or customized shape is needed.Focus on key parametersMaximum operating temperature: Ensure that the upper temperature limit of the tape is higher than your process temperature.Tensile strength: This is particularly important for fiberglass cloth tape, as it directly affects its durability.Adhesive strength: The peeling force on steel is one of the key indicators, for example, 3M 5498 has a peeling force of about 22-48N/100mm on steel.Thickness range: The thicker the thickness, the better the strength and durability.Proper installation and maintenanceThoroughly clean: Before pasting, be sure to thoroughly clean the surface of the mold with a suitable solvent (such as acetone) to ensure that there are no oil stains or impurities, in order to ensure optimal adhesion.Smooth pasting: When pasting, avoid generating bubbles and use a scraper to smooth from the center to the edges.Regular inspection: Regularly check the wear of the tape during production intervals. Once serious scratches or peeling are found on the surface, it should be replaced in a timely manner.Easy replacement: After tearing off the old tape, if there is any residue, it can be removed with alcohol or a special cleaning agent, and then a new tape can be reattached.There are many manufacturers and brands on the market that supply PTFE tape. We suggest that you evaluate from these perspectives in order to find the most suitable "invisible protector" for your die-casting conditions.Friction resistant PTFE high-temperature cloth tape mold compression protection
Friction resistant PTFE high-temperature cloth tape is an industrial tape that combines the excellent non adhesiveness of PTFE with the high strength of glass fiber cloth. It is designed specifically for anti sticking, insulation, and wear resistance requirements in high temperature, high pressure, and high wear environments.It is commonly referred to as PTFE high-temperature tape or PTFE fiberglass tape, made by coating PTFE on fiberglass cloth. Compared with ordinary PTFE film tape, its core characteristics emphasize more on mechanical strength and wear resistance.Core technical parametersFor your convenience in evaluation, the following are the key performance indicators and common specifications of this type of tape:Characteristic Typical Parameters/Specification DescriptionLong term temperature resistance: -70 ℃ to 260 ℃Short term: can reach 280 ℃ -300 ℃ and maintain stability in a wide temperature range, suitable for high temperature conditions.Wear resistant composite glass fiber cloth with high tensile strength (such as 900 N/100mm) is the outstanding advantage of this type of tape. Fiberglass base fabric provides excellent mechanical strength and tear resistance, making it more durable in friction and scratch environments.The extremely low friction coefficient of 0.05-0.1 gives it excellent "non stick" properties, which can effectively prevent material adhesion and assist in sliding.Excellent anti adhesion performance, PTFE coating surface hardly adheres to any substances, including glue, resin, oil stains, etc., making it easy to clean.Excellent corrosion resistance, able to resist corrosion from strong acids, strong bases, and various organic solvents, with high chemical stability.High electrical insulation and dielectric constant<2.6 can be applied in scenarios that require electrical insulation protection.The conventional thickness of 0.08mm to 0.5mm is a key parameter affecting wear resistance and service life, which can be selected according to the application mon colors: brown, black, white, blueOther features include fire resistance, flame retardancy, UV protection, and anti-static. Some products also have these additional functions to adapt to more special environments.Main application areasBased on its characteristics of wear resistance, high temperature resistance, and anti sticking, it is mainly applied in the following scenarios:Packaging and heat sealing industry: used for hot pressing sealing end faces of bag making machines and sealing machines to prevent the packaging film from melting and sticking to the heating block, ensuring sealing quality and production efficiency.Industrial rollers and drying drums: Covering the surface of drying drums in papermaking, printing and dyeing, bonding and other equipment to prevent material adhesion and protect the drum surface from wear and tear.Electronic and electrical insulation: As an H-grade (above 180 ℃) temperature resistant insulation material, it is used for wrapping and insulation protection of coils and cables.Thermoplastic mold demolding: The liner is placed on the mold or heating plate as a demolding medium, making it easy for the formed plastic or composite products to detach without the need for demolding agents.Chemical anti-corrosion lining: used as an anti-corrosion and wear-resistant lining for chemical pipelines, reaction vessels, hoppers and other equipment to protect the equipment substrate.Aerospace: Can be used as a liner for aerospace molds to meet the high temperature and high-precision demolding requirements.Main brands and market reference pricesThere are multiple brands in the market that offer this type of product, and the following are reference information from several mainstream manufacturers:Typical brand models/series reference prices (example) Remarks3M 3M ™ PTFE 5451 and 5453 are internationally renowned brands with high prices (usually measured by roll), stable performance, and offer a variety of width and length specifications.Tesa (tesa) tesa ® 4800 is a high-performance adhesive tape designed by Desha specifically for demolding applications, with a relatively high price (usually calculated by roll), emphasizing mechanical stability and wear resistance.NITTO (Nitto) No.903UL, No.973UL approximately ¥ 143/roll (10m long) is a Japanese brand with a high market share and a rich product line, offering a variety of widths and thicknesses to choose from.Domestic manufacturers such as Qiaorui, Giant Adhesive Tape, and SKF offer high cost-effectiveness at around ¥ 10-35 per roll (10m in length) and flexible customization of specifications, making them widely used in the domestic industrial market.Summary: Friction resistant PTFE high-temperature cloth tape is an industrial tape that integrates multiple properties such as high temperature resistance, wear resistance, anti sticking, and insulation. It is an effective solution to solve the problems of material adhesion and wear under high temperature conditionsThermal anti adhesive protective film
Thermal anti adhesive protective film is a functional thin film material that can significantly reduce or even eliminate its viscosity by heating, thereby achieving no residual adhesive and no damage peeling.Its core lies in a "thermal response" mechanism. Simply put, before heating, it can provide sufficient adhesion to fix and protect the workpiece, just like a regular protective film; After the process is completed, simply heat it to a specific temperature, and the viscosity will sharply decrease (from a few hundred grams of adhesive force to negligible), making it easy and clean to peel off.1、 Core principle: Two mainstream technological routesThere are two main technologies for achieving this "thermal anti sticking" effect, which are currently applied in the market:Foaming type: using microsphere expansion to break the bondThe adhesive layer of this protective film is dispersed with tiny thermal expansion microspheres. After heating, the microspheres rapidly expand and increase in volume, disrupting the continuity of the adhesive layer and causing a sharp decrease in the contact area between the adhesive layer and the surface of the object being adhered, resulting in loss of adhesion.Key indicators: Heating expansion to lose viscosity usually takes only 10 seconds to 5 minutes, depending on the heating temperature and the formula design of the protective film.Peeling effect: It can achieve "automatic peeling", that is, after heating, the adhesive film will automatically arch or fall off from the surface of the workpiece due to the loss of viscosity, greatly improving efficiency.Material phase change type: using special polymer materialsThis is a relatively new technology that does not use foaming agents. It is achieved by adding a specific proportion of liquid crystal material (such as 5% -15% of the total weight) to the acrylic resin adhesive chanism of action: At room temperature, the liquid crystal molecules in the adhesive layer maintain an ordered state, providing high viscosity; After heating, the liquid crystal molecular structure undergoes a thermally induced phase transition, breaking the molecular arrangement of the adhesive and resulting in a significant decrease in its macroscopic adhesion.Advantage: This design can avoid the residual glue problem that may exist in traditional heat reducing films and improve the reliability of peeling.2、 Key characteristics and important parametersWhen choosing a thermal anti adhesive protective film, the main focus is on the following core parameters:Typical numerical range of parameters/explanation of impact and selection suggestionsPeel off temperature low temperature: 90-100 ° CMedium temperature: 120-130 ° CHigh temperature: The core indicator selected is 140-180 ° C. It must be higher than the process temperature during processing, but it cannot be too high to avoid damaging the workpiece that is not heat-resistant.Initial viscosity low viscosity (~200g/25mm)Medium viscosity (~400g/25mm)High viscosity (~700-1500g/25mm) is selected based on the weight of the workpiece and fixing requirements. Excessive adhesion may cause difficulty in peeling off after processing, while insufficient adhesion may prevent firm fixation.After heating, the viscosity usually drops to<10g/25mm, or even lower to 0.02N/20mm, which is the key to evaluating the difficulty of peeling. The smaller the value, the easier the peeling and the lower the risk of damage to the workpiece.The common substrate and thickness are PET (polyester film), as well as high-temperature resistant materials such as PI. The total thickness is usually between 50 μ m and 115 μ m. PET has good comprehensive performance and low cost; PI has better heat resistance. Thickness affects flexibility and strength, and needs to be adapted to the surface and processing method of the workpiece.The core advantage of this product is to have no residual adhesive after peeling, but the compatibility between the product and specific materials needs to be verified in application.3、 Main application areasThanks to its heating and anti sticking properties, thermal anti sticking protective films are widely used in precision manufacturing fields that require temporary fixation and protection, especially in the electronics industry:Semiconductors and Microelectronics: Used for fixing and protecting the backside grinding and cutting process of chip wafers. After cutting, heating can easily pick up individual chips (grains) from the tape without damaging the chips or leaving adhesive residue.Passive component manufacturing: used for cutting, positioning, and handling in the manufacturing process of small components such as MLCC (Multi Layer Ceramic Capacitor) and MLCI (Chip Inductor).Optoelectronics and flat panel displays: used for protection during the thinning, grinding, and polishing processes of LCD/TP touch panel glass.New material processing: used as a temporary carrier and protective layer in the transfer printing process of materials such as graphene and carbon nanotubes.Other applications: including but not limited to cutting and grinding of LED chips, precision metal component processing, ceramic substrate cutting, etcBright black (matte black) polyester film
Bright black (matte black) polyester film is a common functional PET film in industry, characterized by excellent light shielding and mechanical and electrical insulation properties. The choice of two surfaces mainly depends on the different requirements of the application scenario for light parison of core featuresCharacteristics: Bright black polyester film, matte black polyester filmMain features: The surface is bright and smooth, with strong reflectivity, visually more eye-catching.

Some high-quality products will be strengthened by special treatment, which is usually better than the bright facial mask. Tiny scratches are not easy to detect and are more resistant to fingerprintsBoth have excellent shading performance, which can block the majority of light. Some professional grade products have a light transmittance of less than 1%, even reaching 100% full shadingMain performanceRegardless of whether the surface is glossy or matte, this type of film has the following general properties:Electrical insulation: With high dielectric strength, it is an ideal electrical insulation material.High temperature resistance and dimensional stability: It has good temperature resistance, low thermal shrinkage, and can maintain flatness even in high-temperature processing or use environments.High physical strength: possessing high tensile strength and impact resistance.Chemical stability: It has good adhesion to various inks, silicone oils, and coatings, and is resistant to acid and alkali corrosion without fading.Main application areasBased on the above characteristics, its application covers multiple industrial fields:Electronics and Electrical: Light shielding, insulation, and fixation of LCD/LED backlights, mobile phones, and other electronic devices; Insulation outsourcing and inter slot insulation for various transformers, motors, and coils; Used for insulation reinforcement and solder mask of flexible circuit boards (FPC).Acoustics and Optics: Sound and vibration membranes used in electroacoustic equipment such as speakers, headphones, and microphones; As a shading film inside cameras and optical instruments, it absorbs stray light and improves imaging quality.Industry and packaging: used for blister packaging and surface decoration of high demand products; As a substrate for industrial tape (such as shading tape); Panel for membrane switches and nameplatesTranslucent red PET polyester film

It is recommended to request samples from multiple suppliers for comparison.Seeking customization: Most factories accept customization. Products with different light transmittance, customized color codes, anti-static treatment, or special widths and lengths can be requestedGlass cloth tape stuck with silicone adhesive, unable to be peeled off
Using glass cloth tape to stick silicone rubber, common application scenarios include using it as an auxiliary material in FPC (flexible printed circuit board) lamination process, or fixing and protecting silicone components in high temperature environments.Here is a detailed operation guide, hoping to be helpful to you:✍️ preparation in advanceSurface cleaning: This is the most crucial first step. Please use a dry cloth, brush, or dipped in alcohol, acetone, or other cleaning agents to thoroughly remove dust, oil, and impurities from the silicone rubber and the surface of the object being pasted, to ensure a firm adhesion and avoid moisture affecting electronic products during cleaning.Material cutting: Cut the glass cloth tape and silicone rubber into suitable shapes and sizes according to actual needs.📝 Paste core stepsPositioning and pasting: Due to the strong initial adhesion of the glass cloth tape, it is difficult to adjust once it is pasted, so it is necessary to accurately paste it all at once after determining the position. Use the "direct bonding method" to attach the tape to the silicone rubber, and repeatedly press the tape with force to fully utilize the adhesive layer, ensuring no bubbles and tight pression and static placement: In specific processes such as FPC compression, hot pressing is usually required after bonding. Accurate control of parameters such as pressure, temperature, and time is required. After completing the operation, it is best to let it stand for 24 hours to achieve the best bonding strength of the tape, and try to avoid applying external forces to the bonding area during this period.Surface protection and inspection: After pasting, if there is glue overflow, it can be carefully cleaned with a blade. The final step is to carefully check whether the adhesive surface is smooth and free of impurities such as bubbles and particles, to ensure the quality of the bonding.Here are several typical application scenarios that can be referred to:💡 Application scenario referenceFPC hot pressing process: The glass cloth tape is attached to the silicone rubber, which plays a role in buffering, preventing displacement, blocking adhesive overflow, and filling uneven lines during pressing.High temperature equipment fixation: Utilizing its wide temperature resistance range of -40 ℃ to 260 ℃, it is used for sealing, sandblasting protection, coil binding, etc. of high-temperature pipelines.Adhesive of silicone related products: Some special tapes (such as Japan's IPROS G-301 and Desha's 61526) can directly adhere silicone or perform heterogeneous bonding between silicone and other materials.Temporary protection and fixation: used to shield and protect specific parts of precision electronics or household appliances during painting, welding, and other processes, with no residual adhesive after removalFlexible high-temperature epoxy adhesive film for copper-clad laminates
The specialized flexible high-temperature epoxy adhesive film for copper-clad laminates is a key basic material, mainly used to manufacture flexible printed circuit boards (FPCs). It is essentially a conductive adhesive film that has been specially modified to have both flexibility and high temperature resistance.Core technology: Using "toughening" to solve the problem of "brittleness"After curing, pure epoxy resin becomes brittle and has poor fatigue resistance, so it needs to be modified by physical or chemical methods for "toughening". This is the core technology that gives it flexibility. Common modification methods include:Rubber toughening: This is the most common method. By adding toughening agents such as carboxyl terminated nitrile rubber (CTBN) to epoxy resin, its toughness and peel strength can be significantly improved. Research has shown that when 30 parts of CTBN are added to epoxy adhesive, the impact strength of the modified film can be increased by nearly 149.7%.Chemical modification: Introducing chemical groups such as bismaleimide copolymer (BMI) can effectively increase the flexibility of the adhesive film without sacrificing heat resistance.Key performance indicatorsTo evaluate the performance of this adhesive film, the following three indicators should be considered:High peel strength: ensures that the copper foil will not peel off during subsequent processing (such as PCB "subtractive process" etching) of the copper-clad laminate. It is usually required that its peel strength be greater than 1 kgf/cm, but through modification, the peel strength of the adhesive film can reach up to 2.67 N/mm.Flexibility: This is a characteristic brought about by the aforementioned toughening modification, ensuring that it can adapt to various bending scenarios.High temperature resistance: In the lead-free reflow soldering process at 288-320 ℃, there should be no blistering or delamination of the adhesive film to ensure the reliability of the FPC.Application scenarios: From consumer electronics to specialty industriesThe core application of this adhesive film is the production of flexible copper-clad laminates (FCCL). According to different preparation processes, it can be further divided into:The 3-layer FCCL method, which uses adhesive to bond polyimide (PI) film and copper foil, is currently the most widely used process.2-Layer FCCL: does not rely on adhesives, requires higher technology and cost, but also has superior performance, commonly used in high-end products. Some technologically advanced enterprises already have the ability to mass produce such materials.Specific application areas include:Specific application field descriptionHigh density and high reliability flexible circuit boards for consumer electronics products such as smartphones, tablets, and digital cameras.Electronic components that require rigorous environmental testing in special industrial aerospace, military, and high-end medical equipment.Industry chain related enterprisesApplication and R&D: Domestic enterprises such as Shengyi Technology are important manufacturers of flexible copper-clad laminates. Meanwhile, many universities and research institutions are also conducting in-depth research in this field.Equipment and process: Its production process is also crucial. For example, Associate Professor Li Huilu's team at Xi'an University of Science and Technology innovatively uses solvent-free method to produce high thermal conductivity insulation film, which solves the environmental problems caused by traditional solvent evaporation and is applied to high thermal conductivity circuit boardsLOGO sandblasting special heat release protective film
At present, there is no standard product on the market specifically named "LOGO sandblasting special heat release protective film". However, your needs can be met through two mainstream solutions: one is liquid anti sandblasting ink, and the other is solid thermal release protective film. They each have their own emphasis on craftsmanship, precision, and effectiveness.🎨 Solution 1: Anti sandblasting ink - high-precision logo solutionIf your core requirement is to create high-precision logo patterns, then anti sandblasting ink would be a more precise choice. This method is widely used in scenarios such as high gloss LOGO processing on mobile phone metal frames and aluminum alloy product surfaces.Working principle: A hard protective layer is formed on the surface of the substrate through screen printing, exposure development, or spray coating processes. This layer of ink can withstand the impact of sandblasting, protect the areas that need to be preserved, and achieve precise etching of logos or patterns.Core advantage: High precision, photosensitive development ink can achieve a resolution of 20 μ m, fully meeting the production needs of fine logos. The curing time of UV curable ink is only 5 seconds, suitable for large-scale production.Removal method: After sandblasting, it can be soaked in dilute alkali solution (such as 5% NaOH solution) or mechanically peeled off without leaving any residue.Key parameters: Impact resistance of approximately 0.2-0.5MPa; The ink film layer has high elasticity and sand resistance.Supplier reference: Shenzhen Wanjia Yuan Fine Chemical Technology Co., Ltd. is one of the suppliers of this type of ink.🛡️ Option 2: Thermal anti sticking protective film - convenient overall protectionIf considering the use of solid film, it is mainly used for masking and temporary fixation before sandblasting, rather than directly as logo ink. For example, sticking a logo masking film on aluminum alloy products before sandblasting is a typical application.Working principle: Maintain viscosity at room temperature, used to protect or fix workpieces. After processing, by heating to a specific temperature (such as 100 ° C to 180 ° C), its viscosity will sharply decrease (foaming peeling), making it easy to remove.Core advantage: No residual glue is its most prominent advantage, and it will not contaminate the surface of the protected object after heating and peeling. Easy to use, can be peeled off after processing.Key parameters: The conventional adhesion force is relatively high at room temperature and decreases to about 0.02N/20mm after foaming; The peeling time usually ranges from 10 seconds to 5 minutes.In addition to thermal anti adhesive protective films, traditional sandblasting protective films (such as PVC materials) used for sandblasting protection are also widely used, especially for large-area protection.🔩 Key Process and Structural AnalysisComparison of core processes:Anti sandblasting ink process: cleaning → silk screen printing/spraying ink → curing (UV or hot air) → sandblasting → peeling.Protective film process: cleaning → film application (cold/hot pressing) → sandblasting → heating peeling.The structure of sandblasting protective film is usually a three-layer composite structure, including the surface layer, middle layer, and adhesive layer. For example, a common structure is: PVC film+gelatin (water-based adhesive)+release paperMLCC upper/lower tape coated with silver tape
In the production of MLCC (Multi Layer Ceramic Capacitors), the "upper/lower tape" and "silver dipping tape" you asked about are two completely different specialized tapes that play important roles in packaging, transportation, and electrode manufacturing, respectively.📦 Cover/Base TapeThis type of tape is mainly used for packaging and transportation of electronic components. They are used in conjunction with paper carriers to securely seal small components such as MLCC in the grooves of the carrier for accurate picking on automated surface mount machines.Core requirement: To prevent tiny MLCC from being electrostatically broken down, this type of tape usually needs to undergo anti-static treatment. At the same time, they also need to have stable peeling force (pulling force) to ensure that they can be smoothly peeled off on the automatic mounting machine without leaving irregular tear marks.Main suppliers: Major players in the industry include Japan's Mattei Group, Jiemei Technology, and some professional manufacturers such as Taicang Qunte Electrical Materials.🎨 Silver Termination TapeThis type of tape is used in the "sealing" process of MLCC manufacturing to protect the ceramic body parts that do not require sizing. Due to the need to be exposed to high temperatures, it has high requirements for heat resistance.Working principle: When silver paste (or copper paste) is applied to the end of MLCC to form an external electrode, this tape tightly wraps around the rest of the capacitor, providing shielding and protection. Subsequently, the components with adhesive tape will enter a high-temperature oven or sintering furnace for processing.Core technical requirements:High temperature resistance: This is the most critical characteristic. After high-temperature treatment at 200 ° C to 260 ° C, the performance of the tape must remain stable and cannot deform or melt.No residual adhesive: When peeled off after the process is completed, it must be 100% residue free. Any residual adhesive will affect the performance or appearance of MLCC.Flexible and snug: The tape needs to be able to tightly adhere to the tiny surface of MLCC, providing reliable shielding for subsequent electroplating, sintering, and other processes.Main suppliers: The main suppliers in the market include Shenzhen Yizhong Technology Co., Ltd., Dongguan Xinpengda Adhesive Products Co., Ltd., Haojia Enterprise Co., Ltd., Shenzhen Youtu Technology, etc.⚙️ New choice in technology: thermal foaming tapeIn the "silver dipping" process, in addition to traditional silver dipping tape, a more advanced thermal foaming tape is becoming popular.Traditional silver coated adhesive tape needs to be manually or mechanically removed after protection, while thermal foam tape utilizes its own characteristics to rapidly expand in volume at specific high temperatures (about 190-210 ° C), thereby automatically and completely eliminating the stickiness and achieving automatic unloading of components. This characteristic makes it more suitable for high-precision automated production and can effectively avoid the physical damage that traditional tape may cause to fragile ceramic bodies or electrodes when torn off, especially when dealing with small-sized MLCCsWater soluble double-sided tape
Water soluble double-sided tape, also known as "water soluble" or "re wettable" double-sided tape, is a special type of tape that can be rendered adhesive and achieve environmentally friendly separation by water.It is composed of water-soluble substrates (such as specialty paper, non-woven fabric) and water-soluble adhesives (usually modified acrylic acid), which can decompose or dissolve when exposed to water. Its core advantage lies in the ability to avoid non water soluble materials from polluting the recycling system, ensuring resource reuse.Application areas: from industry to daily lifeThe application of water-soluble double-sided tape is mainly divided into two categories: industrial grade and civilian grade.⚙️ Industrial sector (mainly paper and printing industry)Paper Flyover/Automatic Splicing: Used in high-speed production of roll paper to connect new and old paper rolls, the tape can be completely dissolved in the subsequent pulp making process without affecting pulp quality and equipment.Rolling and sealing: Fix the paper on the core or stick the tail of the roll to ensure no residue and no impact on recycling.🧵 In the civilian/handmade field (mainly Japanese brands such as Clover Cola)Temporary fixed fabric: used to temporarily fix fabrics, lace, zippers, etc. during *ing. After *ing, they can be removed by soaking in water to avoid thread removal or fabric damage.Making a water-soluble embroidery substrate: As a base for embroidery, it dissolves in water after completion, leaving only exquisite embroidery pieces.Other applications: It can also be used for medical sealing, environmentally friendly packaging, special anti-counterfeiting labels, etc.Mainstream brands and productsInternationally renowned tape brands all offer water-soluble product lines, mainly serving the industrial market.Tesa: Provides a comprehensive product line, such as the CaRes series and EasySplice series, some of which use patented calcium resistant technology to adapt to hard water environments. In the series, there are pure adhesive films without substrates (such as tesa) available ® 51916), as well as paper substrates (such as tesa) ® 51914) and other options.3M: Its water-soluble tape (such as the R996 series) adopts a double-layer design, and the tape itself can be directly peeled off from the lining for easy operation.Nitto (Nitto): Model number 509A, made of non-woven fabric substrate, suitable for automatic splicing in papermaking.Clover: mainly targeting the handicraft market, the product is compact and specifically designed for temporary fixation of fabrics.Other: There are also Orafol (such as ORAFIX) on the market ® 12885), Sharktope, and numerous domestic brands to choose from.Key technical parametersWhen purchasing, please pay special attention to the following indicators:Solubility: Pay attention to its repeatability, which means whether it can be fully decomposed in water without producing clumps.Adhesive force: Water soluble tape usually has high initial adhesive force to meet the needs of temporary fixation.Temperature resistance: Different products have significant differences in temperature resistance. 3M R996 tape can withstand high temperatures up to 204 ° C for a short period of time, while ordinary products may only be used at room temperature.PH adaptability: Some products (such as tesa) claim to dissolve well within the pH range of 3 to 9.Selection and usage precautionsClear application scenarios: Industrial applications should choose models with high adhesion and rapid dissolution; For manual use, attention should be paid to whether it is suitable for specific fabrics and whether there is no residue after *ing.Pay attention to environmental certification: Check whether the product meets FDA (Food and Drug Administration) food contact level standards or TAPPI (Pulp and Paper Industry Technical Association) re pulp standards to ensure environmental safety.Storage conditions: It must be stored in a cool and dry place to avoid the performance degradation of the tape caused by high temperature and humidity.In summary, the core advantage of water-soluble double-sided tape lies in its ability to separate from water, mainly serving the industrial sector that pursues environmental protection and efficient production, and playing an important role in fine handicrafts.
