High temperature tape usually refers to adhesive materials that can maintain good adhesion under certain high temperature environments, mainly including single-sided tape and double-sided tape. These tapes have a wide range of applications in the manufacturing of industrial electronic products, and their high temperature resistance is mainly manifested in their ability to maintain stability under temperature conditions between 120 degrees and 260 degrees. The temperature resistance of high-temperature adhesive tape mainly depends on the properties of its substrate and adhesive. Several common high-temperature adhesive tapes on the market currently include PET polyester film substrate coated acrylic adhesive, PET polyester film coated high-temperature silicone adhesive, PI polyimide film coated acrylic adhesive, PI polyimide film coated high-temperature silicone adhesive, and PTFE tape. These high-temperature tapes have different temperature resistance properties,PET polyester film substrate coated with acrylic adhesive, available in transparent, brown (gold finger), green, black, and other colors. This material generally has a long-term temperature resistance of between 130-150 degrees and a short-term temperature resistance of up to 180 degrees (within half an hour).PET based polyester film coated with high-temperature silicone, available in transparent, brown (gold finger), green (commonly known as green silicone), black, and other colors.

Detailed explanation of polyimide high-temperature tape
High temperature tape is a type of adhesive tape mainly used in the electronics industry for use in high-temperature working environments. High temperature tape includes KAPTON high-temperature tape, PTFE high-temperature tape, high-temperature textured paper tape, PET green high-temperature tape; High temperature double-sided tape, etc. Today, the editor will focus on introducing KAPTON high-temperature tape, also known as polyimide tape. Polyimide tape Also known as KAPTON tape, gold finger tape, PI tape, it is made by coating a polyimide film substrate with high-temperature resistant adhesive. There are two types of materials: single-sided fluoroplastic release material composite or non composite. Material characteristics Polyimide tape has excellent insulation, durability, acid and alkali resistance, and temperature resistance.

Foam plastic: used as high temperature resistant and heat insulating material. Engineering plastics: There are thermosetting and thermoplastic types, and thermoplastic types can be molded by compression molding, injection molding, or transfer molding. Mainly used for self-lubricating, sealing, insulation, and structural materials. Separation membrane: used for the separation of various gases, such as hydrogen/nitrogen, nitrogen/oxygen, carbon dioxide/nitrogen, or methane, to remove moisture from air hydrocarbon feed gases and alcohols. It can also be used as a pervaporation membrane and ultrafiltration membrane. Photoresist: Some polyimides can also be used as photoresists. There are negative and positive adhesives, and the resolution can reach sub micron level. When combined with pigments or dyes, it can be used for color filter films, greatly simplifying the processing steps. Application in microelectronic devices: used as a dielectric layer for interlayer insulation, and as a buffer layer to reduce stress and improve yield. As a protective layer, it can reduce the impact of the environment on the device and also act as a shield for alpha particles, reducing or eliminating soft errors in the device. Polyimide, an alignment agent used in liquid crystal displays, plays a very important role in the materials of TN-LCD, SHN-LCD, TFT-LCD, and future ferroelectric liquid crystal displays.Electro optical materials: used as passive or active waveguide materials, optical switch materials, etc. Fluorinated polyimides are transparent in the communication wavelength range, and using polyimide as a chromophore matrix can improve the stability of the material. Moisture sensitive materials: The principle of linear expansion due to moisture absorption can be used to make humidity sensors. Storage method 1. Tape should be stored in the warehouse to avoid direct sunlight and rain; Do not come into contact with acidic, alkaline, oil or organic solvents, keep clean and dry, and keep a distance of 1 meter from the discovery device. The room temperature should be between -15 ℃ and 40 ℃. 2. The tape should be placed in rolls without folding. If stored for too long, it should be flipped once every season. 3. It is best to use a crane when loading and unloading the conveyor belt, and use rigging with crossbeams to lift it steadily to avoid damaging the edge of the belt. Do not load or unload recklessly, which may cause loose rolls and loose sleeves. 4. The type and specifications of the tape should be selected reasonably according to the usage needs and specific conditions. 5. Do not connect tapes of different varieties, specifications, strength, and fabric layers together for use. 6. It is best to use hot vulcanized rubber joints for conveyor belt joints to improve reliability and maintain high effective strength. 7. The diameter of the conveyor roller and the minimum pulley diameter of the conveyor belt should comply with relevant regulations. 8. Do not make the tape snake or crawl. Keep the rollers flexible and the tension moderate. 9. When the conveyor is equipped with baffles and cleaning devices, wear and tear on the tape should be avoided. 10. Cleanliness is a basic condition for the good operation of adhesive tape. Foreign substances can affect tape eccentricity, tension differences, and even breakage. 11. When early damage to the tape is found during use, the cause should be promptly identified and repaired to avoid adverse consequences.Quality requirementThe quality of polyimide tape is very important. Have you ever learned about the quality requirements of polyimide tape? Let me take a look.1、The adhesion of polyimide tape should be long-lasting and should not dry out after a period of time;2. When tearing off the polyimide high-temperature tape, it should be able to be completely removed;3. When removed after completion, the polyimide tape should not have any residue or images;4. After long-term bonding of polyimide tape, there should be no bubbles floating or curled edges;5. Polyimide tape must have weather resistance when used outdoors; 6. Polyimide tape must not have crystal dots.The way to distinguishAt present, there are many manufacturers of polyimide tape on the market, and the product quality is also uneven. Is there any way to identify the authenticity of polyimide tape? Now, the editor will bring you a method to identify authenticity.1、Looking at the appearance, generally speaking, low-quality high-temperature tape has a slightly dull color, while high-quality gold finger high-temperature tape has a relatively good surface gloss.2. Look at the residue after ignition, bake with a lighter for 1 to 2 seconds, and then touch with your hand. The high-temperature tape of the golden finger really won’t stick to your hands.3. In actual high-temperature testing, after passing through a high temperature of 260 ° C, check for residual glue, shrinkage, and other phenomena, because the temperature resistance of real gold finger high-temperature tape is usually between 120 ° C and 260 ° C.Definition of Polyimide Industry

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. The surface has a fine sand texture, low glossiness, and can reduce light reflectionHigh and extremely low glossiness (some products may have glossiness as low as 2.5%)Wear resistance/scratch resistance is relatively easy to develop. Some high-quality products will be strengthened by special treatment, which is usually better than the bright facial mask.

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.Flame retardant aluminum foil fiberglass cloth tape
