2026-03-06Application areas of polyimide
Polyimide (PI) has a wide range of applications, mainly including the following aspects: 1.Aerospace: Polyimide has important applications in the aerospace field. Due to its excellent thermal stability and mechanical properties, it is commonly used in the manufacturing of structural components, insulation materials, and high-temperature resistant coatings for aircraft and rockets 2.Microelectronics and Nanotechnology: Polyimide is also widely used in the field of microelectronics, known as “without polyimide, there would be no microelectronics technology today”It is commonly used in chip packaging, flexible circuit boards (FPCs), and flexible display technology, especially in the substrate materials of flexible OLED screens. Polyimide film is widely used due to its superior performance 3.New energy: In the field of new energy, polyimide films and composite materials are used as separators and packaging materials for lithium-ion batteries, improving the safety and performance of the batteries munication and chip packaging: Polyimide also plays an important role in communication equipment, used to manufacture high-performance printed circuit boards and chip packaging materials, ensuring stable operation and long lifespan of equipment 5.Automotive industry: In the automotive industry, polyimide is used to manufacture high-performance automotive components and wires and cables, improving the heat resistance and electrical performance of automobiles dical equipment: Polyimide is also used in medical devices to manufacture high-precision medical devices and components, ensuring the reliability and durability of the equipment 7.In the field of optics, polyimide is also used to manufacture optical components such as optical filters and lenses 8.Other fields: In addition, polyimide is also used in nuclear energy, satellite technology, separation membranes, lasers, and other fieldsGlass 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 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. When peeled off in high temperature environments, the tape will not leave stubborn adhesive stains, making it very suitable for occasions that require clean surfaces.Core performance characteristicsExcellent high temperature resistance: This is its core selling point. Depending on the specific product, its temperature resistance range is usually between -50 ℃ and 260 ℃. Taking the well-known brand 3M's 361 # tape as an example, it can withstand a temperature range of -54 ℃ to+232 ℃ and can intermittently withstand high temperatures up to+288 ℃. 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 #. If you have used these models before, you can easily find alternativesPCB circuit board high-temperature resistant fixed edge protection tape

The FRT-0002B from Saiwu Technology is a typical representative of this type of productFlame retardant aluminum foil fiberglass cloth tape
Flame retardant aluminum foil glass fiber cloth tape is a composite tape made of aluminum foil and glass fiber cloth as substrates, coated with flame retardant adhesive. It combines the high reflectivity of metal aluminum foil, the mechanical strength of fiberglass cloth, and the adhesive properties of the adhesive, while possessing the core characteristics of fire resistance and flame retardancy.Core technical parametersThe parameters of different manufacturers and models may vary, and the following are common technical indicators:Common project standards/numerical notesThe total thickness is 140-190 μ m (0.14-0.19 mm), and different thicknesses can be selected according to application requirementsThe common thickness of aluminum foil is 0.007 mm, and there are also specifications such as 18 micronsFiberglass cloth specification density: 12 × 14 or 14 × 14 (unit: roots/inch) affects the overall strength of the tapeAdhesive type: Flame retardant acrylic adhesive provides adhesive strength and meets flame retardant requirementsPeel strength (180 °) ≥ 0.55 KN/m tested according to GB/T 2792 standardAdhesive strength ≥ 24 hours, tested according to GB/T 4851 standardThe applicable temperature range is -20 ℃ to 70 ℃. This is the working range of the adhesive, and there are differences among different brandsMain application areasDue to its excellent comprehensive performance, this tape is widely used in insulation, fire prevention, and sealing scenarios in multiple industries:HVAC and Architecture: Used for sealing and repairing joints in air conditioning ventilation ducts and insulation layers.Industrial pipelines: used for protective wrapping and external insulation of petroleum, chemical, and steam pipelines.Transportation: Used for insulation, noise reduction, and fire prevention in car, train, ship carriages or cabins.Special equipment: applied in fields such as high-speed trains and bullet trains that have strict requirements for fire protection levels.Electronics industry: used for electromagnetic interference (EMI) shielding of electronic devices.Packaging protection: Packaging materials that are moisture-proof, mold proof, fireproof, and anti-corrosion for export equipmentLOGO 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 paperElectrical 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.Plasma spraying tape

Epoxy thermoplastic composite film is a high-performance adhesive material, whose core feature is to combine thermosetting epoxy resin with thermoplastic resin (such as polysulfone, nylon, etc.), usually in the form of a thin film, mainly used for bonding and manufacturing composite materials.To help you understand more clearly, we can look at the following aspects:1. What is it? ——A type of adhesive film that combines rigidity and flexibilityEpoxy resin itself is hard and heat-resistant, but relatively brittle; And thermoplastic resin is very flexible. The combination of the two is to allow epoxy resin to retain its high strength and heat resistance advantages while increasing toughness through thermoplastic resin, solving its "brittle" weakness.Form: It usually exists in the form of a solvent-free film, with very precise thickness and resin content, making it easy to operate and process control.Curing: When in use, it requires a chemical reaction at a certain temperature to cure (crosslink) and ultimately form a strong bond.2. Core advantage: Why add thermoplastic resin?Adding thermoplastic resins (such as polyethersulfone, nylon, etc.) to epoxy resins for modification mainly brings three major benefits:Significantly improving resilience: This is the primary objective. Research has shown that adding 20% thermoplastic resin can increase the impact strength of composite materials by 154% and the bending strength by about 50%.Ensure high strength: While increasing toughness, it can still maintain the excellent cohesive strength and heat resistance of epoxy resin. For example, a patented product has been toughened with thermoplastic resin, increasing its temperature resistance level to 175 ℃ and achieving a glass transition temperature (Tg) of 190 ℃.Good process performance: The adhesive film is easy to lay and suitable for bonding large and complex structural components. There are almost no volatiles during curing, ensuring the density of the adhesive layer.3. Main application scenariosDue to its excellent comprehensive performance, this adhesive film is mainly used in high-end fields:Aerospace: This is the most important application field. Used for manufacturing and bonding aircraft structural components (such as wings, fuselage), radar antenna covers, engine nacelles, etc., it needs to withstand extremely high stress and temperature changes.Rail transit: used for the manufacturing and assembly of lightweight components for trains, such as bonding carbon fiber bodies and interior parts, to meet the weight reduction and strength requirements of high-speed trains.Sports equipment and electronics: also used for manufacturing high-performance sports equipment (such as tennis rackets, bicycle frames), as well as for bonding electronic components that require high reliability.4. Typical product casesTo give you a more intuitive understanding, here are two typical products on the market:Product Name Key Features Typical Application SourcesThe Henkel LOCTITE EA 9658 is designed specifically for engine nacelles, with three times the toughness of similar products, and can be used for a long time at 177 ℃ (tested for 6000 hours). Aerospace (bonding of composite materials, metals, honeycomb materials)3M ™ AF 325LS is a surface adhesive film containing copper mesh, which has both conductivity and surface leveling functions. Working temperature range -55 ℃ to 149 ℃, can be co cured with prepreg. Aerospace (composite material surfaces requiring lightning protection)summarySimply put, "epoxy thermoplastic composite film" is a high-performance film adhesive made by combining strong and tough epoxy resin with flexible thermoplastic resin. It not only retains the heat resistance and high strength of epoxy resin, but also solves its brittleness problem through thermoplastic resin, making it an indispensable key material in high-end manufacturing industries such as aerospace.Glass fiber cloth heating joint adhesive film
The current mainstream solution on the market is adhesive tape products based on glass fiber cloth and coated with high-temperature resistant adhesive, rather than independent adhesive films. This type of product can achieve strong joint bonding through heating and coordination.To help you make a clearer selection, I have compiled a table of the technical parameters and types of these products.1. Quick search for technical parameters of mainstream productsAccording to information from multiple manufacturers, the typical "heating joint" on the market uses fiberglass cloth tape, and its core parameters are shown in the following table:Parameter Type Typical Value/Description Data SourceBase material alkali free glass fiber clothThe adhesive type is mainly organic silicon pressure-sensitive adhesive, and there are also acrylic pressure-sensitive adhesivesThe thickness of the product is usually between 0.17mm and 0.22mmThe long-term temperature resistance is generally around 220 ° C, and some products can reach 260 ° CHigh tensile strength, such as ≥ 420 N/25mm or 600 N/25mmGood insulation performance, with flame retardancy and electrical insulation (H-level)2. Selection suggestions for different types of productsAccording to specific application requirements, you can choose from the following types:Pursuing permanent and high-strength bonding (such as composite structural bonding):Recommendation: Choose "thermosetting" or "thermosetting" glass cloth tape. This type of tape undergoes a chemical reaction after heating, forming a stronger and more durable bond, suitable for scenarios such as transformers and motor coils that require long-term reliable fixation.Pursuing convenient operation, temporary fixation or wrapping (such as fixation in heating processes, cable joint wrapping):Recommendation: Choose glass cloth tape coated with silicone pressure-sensitive adhesive. It only requires finger pressure to adhere, and heating (such as using heating tools) can further soften the gel, making it better adhere to the irregular surface, achieving a firm and residue free fixation. Especially suitable for wrapping mine cables, high-temperature coils, etc.Double sided bonding or special adhesive requirements are required (such as fixing nameplates, irregular parts):Recommendation: Consider double-sided glass cloth tape. For example, some manufacturers offer products with different viscosities on A/B sides (weak adhesion on one side and strong adhesion on the other), which can adapt to more complex production process requirements.3. Procurement and Channel ReferenceThese products are mostly industrial products, and you can purchase and consult through the following channels:Online B2B platforms, such as Alibaba International, have a large number of suppliers who can be screened based on product parameters and user evaluations.Professional tape manufacturers: Kunshan Yaheng Electronic Technology, Suzhou Changying Electronic Technology, Penglai Xicheng Insulation Materials, Suzhou Yunqi Adhesive Products and other companies mentioned in the search results are all professional manufacturers of such products. You can directly contact them for technical support or samples.Brand Agent: If you prefer international brands, you can look for authorized agents for similar models of adhesive tape (such as 3M 27 #, 3M 69 #) from 3M Company.To summarize: If your application is permanent structural bonding, you can focus on "thermosetting" silicone tape; If it is a field joint or fixation that requires flexible operation, then "pressure-sensitive" silicone glass cloth tape would be a more suitable choice. Before placing an order, it is best to contact the supplier to confirm whether the specific curing conditions and temperature resistance of the product fully meet your requirementsAviation honeycomb sandwich epoxy film adhesive
Aviation honeycomb sandwich epoxy adhesive film "is a high-tech composite material. Simply put, it is like an ultra high strength" industrial double-sided adhesive ", specially used to firmly bond the skin of an aircraft (such as carbon fiber board) and the honeycomb core material inside, forming what we often call a" sandwich "structure. This structure is both light and strong, widely used in components such as aircraft wings, radar covers, and floors.At present, the mainstream products in the market are mainly divided into two camps: international and domestic, each with its own characteristics. For your convenience in comparison, I have compiled a table:✈️ Main product comparisonProduct Model/Series Manufacturer/Source Core Features Typical Application Scenarios3M ™ AF 163-2 is a classic product widely used in the international aviation field by 3M Company (International). High toughness, good peel strength, and can be cured at medium temperatures (about 120 ° C). There are multiple models to choose from.

It expands and fills gaps during curing, and is mainly used for splicing, local reinforcement, and edge sealing between honeycomb corematerials. Used in conjunction with J-95 and other structural adhesive films for the manufacturing of honeycomb sandwich structural components in civil aircraft.The SY series (such as SY-14) of AVIC Beijing Institute of Aeronautical Materials is a large family. In addition to the above-mentioned products, there is also SY-14, which can be used for a long time at higher temperatures (about 178 ° C), with high strength and good aging resistance. Suitable for aircraft components with higher operating temperatures, such as flaps.💡 Key considerationsIn practical selection and application, there are several key points that need special attention:Selection points: The choice of adhesive film mainly depends on the curing temperature (matching with the production process), mechanical properties (such as shear and peel strength), and surface density (i.e. thickness).Process matching: The adhesive film is usually not used in isolation and needs to be matched with specialized base adhesive (such as SY-D9 with SY-24C), foam adhesive (such as J-97), etc. to form a complete bonding system.Application environment: Different adhesive films have different long-term use temperature ranges. For example, SY-24C can reach -5570 ° C, while SY-14 can reach -55175 ° C, which needs to be selected according to the actual working environment of the component.Surface treatment: To achieve a strong and durable bond, cleaning and treatment of the bonded surface (such as degreasing, anodizing, etc.) are crucialFlame-retardant PET double-sided tape
Flame retardant PET double-sided tape is a special industrial tape designed specifically for fields with strict fire safety requirements such as electric vehicle batteries and electronic products. It is usually made of PET polyester film as the substrate and coated with flame retardant acrylic adhesive on both sides. While it has excellent bonding performance, the key is to meet the flame retardant level requirements of international standards such as UL94.🔥 Core FeaturesIts main features can be summarized into the following three points:Excellent flame retardant safety: The tape itself is not easy to burn or extinguish immediately upon ignition. The mainstream flame retardant rating is UL 94 VTM-0, which is a common high standard requirement for the flame retardant performance of thin materials in the industry.Reliable physical properties: With PET as the base material, the tape has good dimensional stability, high temperature resistance (long-term temperature resistance can reach 120-125 ℃) and aging resistance, and is easy to die cut.Environmental compliance: Most high-quality flame-retardant PET double-sided tapes on the market do not contain halogens and comply with environmental regulations such as RoHS and REACH.🛠️ Representative products and applicationsDifferent brands of flame retardant PET double-sided tape have different emphasis on thickness and adhesion to adapt to different application scenarios.
