The key lies in whether the tape leaves adhesive residue after being removed, which is primarily determined by its "adhesive (back adhesive)" type and "usage conditions" (temperature, time, surface material).Below, we present a categorized introduction to several mainstream tapes that are resistant to high temperatures and do not easily leave adhesive residue:1. Best choice (high temperature and almost no residual adhesive)This type of tape utilizes silicone pressure-sensitive adhesive or a special formula and is specifically designed for clean removal after exposure to high temperatures.Polyimide high-temperature tape (Goldfinger tape)Material: Brown/Amber film.Temperature resistance: Long-term temperature resistance up to 260°C, and short-term temperature resistance up to over 300°C.Features: One of the most commonly used and reliable options. It often comes with release paper on the back. Its silicone adhesive formula, when used correctly (such as removing it while hot after high temperatures), usually leaves no residue. It is widely used in SMT reflow soldering, wave soldering, circuit board protection, and coil winding.Note: Poor-quality products may still leave residue due to inadequate glue formula.Teflon high-temperature tape (PTFE tape)Material: White/Black, with an extremely smooth surface.Temperature resistance: Capable of withstanding temperatures up to 260°C - 300°C.Features: Excellent anti-adhesive property, inherently non-stick material, thus leaving almost no residue. Commonly used in thermoplastic sealing machines, iron soleplates, baking molds, and chemical anti-adhesive applications. The disadvantage is its low strength and relatively high price.2. Cost-effective choice (for medium and high temperatures, leaving no residue when used correctly)PET green/white high-temperature tapeMaterial: green or white polyester film.Temperature resistance: approximately 130°C - 180°C.Features: Good insulation and a certain degree of toughness. PET tape specifically designed for electronic and electrical purposes (not ordinary packaging tape) uses high-temperature resistant glue. After being used at rated temperature and time, it can be removed without leaving any residue. It is commonly used for circuit board masking, coil insulation, and milder soldering protection.3. Dedicated for shielding protection (medium and low temperature, special formula)High-temperature resistant masking tapeMaterial: crepe paper + special high-temperature resistant glue.Temperature resistance: Varies from 80°C to 220°C depending on the grade.Features: Designed specifically for masking processes such as spray painting, paint baking, and sandblasting. High-quality high-temperature masking tape (such as automotive spray painting grade) should be used within the specified temperature and time range (usually clearly indicated), and should not leave adhesive residue after removal. Using it for too long or at excessive temperatures can result in adhesive residue.Applications: automotive painting, furniture baking paint, glass/ceramic spraying and color separation.Selection and use of core recommendationsDetermine temperature and duration: Ask yourself "What temperature tolerance is required? How long does it need to last?" Choose a tape with a temperature tolerance range higher than your actual needs.Choose specialized tape: Do not substitute with regular tape. For electronic soldering, choose polyimide tape; for painting, choose high-temperature masking tape.Purchase premium brands: Glue formulas from renowned brands such as 3M, Nitto, Tesa, Saint-Gobain, etc., are more stable and carry a lower risk of leaving adhesive residue. Be wary of products with excessively low prices.Test! Test! Test!: Before large-scale or critical applications, it is essential to conduct small-scale testing in inconspicuous places to evaluate its temperature resistance and the effect after removal.Remove while hot: Some high-temperature tapes (such as polyimide tape) will solidify after cooling, making them harder to remove and prone to leaving adhesive residue. It is recommended to remove them while they are still warm, before they have fully cooled down to room temperature.To directly answer your question, after specifying the required parameters (temperature, time, surface), select the corresponding type ofhigh-quality high-temperature resistant tape and operate it according to its usage specifications (especially the timing of removal), and youcan achieve high temperature resistance without leaving adhesive residue. For the most demanding dust-free environments(such as semiconductor and optical industries), there are more specialized ultra-low residue tapes available for selection.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

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.

At the same time, it is necessary to examine whether the adhesive strength of the tape to specific bonding materials (such as aluminum, ABS plastic, foam, etc.) is sufficient.Pay attention to environmental compliance: For export products or enterprises with strict environmental requirements, it is necessary to confirm whether the tape does not contain halogens and complies with the RoHS directive.Anti-static gold finger tape
Anti static gold finger tape is essentially a special tape that adds anti-static (ESD) function on the basis of ordinary gold finger tape (polyimide tape). It is mainly used in the field of electronic manufacturing and maintenance, protecting precision electronic components while preventing static electricity accumulation from causing damage to the components.🛡️ What is it?Its core is polyimide film (PI film), which is an excellent engineering plastic with inherent characteristics such as high and low temperature resistance and electrical insulation. Anti static adhesive tape is based on this and modified through special processes or materials to control its surface resistance within a specific range (usually between 10 ⁹ and 10 ¹² Ω), thereby gently conducting static electricity away and avoiding electrostatic discharge (ESD) from penetrating sensitive electronic chips.📝 Core parametersThe following table summarizes the main performance parameters of anti-static gold finger tape for your quick understanding:Typical characteristics/numerical descriptions of parameter dimensionsThe substrate polyimide (PI) provides the basic properties of high temperature resistance and insulation, and its color is usually brown or amber.The long-term temperature resistance is 260 ℃, and the short-term temperature resistance is 300 ℃. It can withstand high temperature processes such as reflow soldering and wave soldering without melting or deformation.The surface resistance of anti-static performance is 10 ⁹~10 ¹² Ω, which meets the key indicators of ESD standards and ensures safe dissipation of static electricity, rather than instantaneous conduction or insulation accumulation of charges.The silicone pressure-sensitive adhesive has moderate adhesive properties and can firmly adhere at high temperatures. It is also not easy to residue after tearing off.The thickness is usually very thin between 0.05mm and 0.08mm, suitable for tight fitting of precision components.The insulation withstand voltage can reach over 5KV, providing good electrical insulation protection and preventing short circuits.🔧 Main application scenariosIts core value lies in "protection", mainly used in the following scenarios:PCB soldering protection: During SMT (surface mount technology) reflow soldering or wave soldering, it is attached to the gold fingers of the circuit board to prevent contamination or oxidation by solder.Precision electronic maintenance: used in the maintenance of mobile phones, tablets, computers, etc., to temporarily protect sensitive areas such as battery contacts, motherboard interfaces, and cable sockets. The anti-static function is crucial here, as it can prevent the breakdown of precision CPUs, memory chips, etc. by static electricity carried by the human body or tools during the maintenance process.Lithium battery manufacturing: used for insulation and fixation of lithium battery cell lugs.Electronic component insulation: used for high-temperature insulation wrapping of components such as transformers, motors, coils, etc.💡 How to choose correctly?To choose truly useful anti-static tape, don't just look at the color, pay attention to the following points:Confirmation identification: The product must be clearly labeled with the words "anti-static", "ESD" or "Anti static". Only known as "golden finger tape" or "high-temperature tape" usually does not have this function. For example, the well-known brand 3M's 5413 series is a recognized anti-static gold finger tape product.Check parameters: You can refer to the product manual, and the surface resistance value should be between 10 ⁶ and 10 ¹¹ Ω (anti-static standard range).Select specifications based on the scenario:Personal repair or small batch: Purchase a regular length of 5-33 meters, and choose the width according to the protection area. For example, 5mm or 8mm width is suitable for protecting phone battery contacts, while 10mm to 25mm width is suitable for protecting PCB metal fingers.Industrial production: can be purchased in bulk, and specifications (width, length, inner diameter of the tube core) can usually be customized.Acrylic foam double-sided tape
Acrylic foam double-sided tape "is a very important category of industrial tape, which combines high-performance acrylic adhesive with foam substrate to create a bonding solution with excellent comprehensive performance. It is irreplaceable by traditional liquid adhesives and ordinary tape in many fields.Below is a comprehensive analysis of its structure, characteristics, types, applications, and selection points.1、 Core Structure and Working Principle: A Exquisite 'Sandwich'Foam substrate (intermediate layer):Material: Usually polyurethane foam, polyethylene foam, or acrylic foam. Each material varies in softness, density, temperature resistance, and solvent resistance.Core functions:Buffer and shock absorption: absorb impact and vibration energy, protect adhesive components.Filling gaps: capable of filling small unevenness, gaps or tolerances between two adhesive surfaces, achieving full surface contact, which is not possible with hard tape (such as PET tape).Stress dispersion: Uniformly dispersing the adhesive force over a larger area, reducing stress concentration caused by thermal expansion, contraction, or deformation, and improving long-term reliability.Sealing: It has a certain degree of dust, moisture, and sound insulation effects.Adhesive layer (upper and lower layers):Material: High performance acrylic pressure-sensitive adhesive.Core advantages:Excellent weather resistance: resistant to ultraviolet rays, oxygen, and moisture, long-term outdoor use (such as cars, outdoor signs) will not easily yellow, powder, or lose stickiness, and the lifespan can reach several years or even more than ten years.Excellent adhesion: Strong creep resistance under sustained stress, not easy to slip or detach.Wide material adaptability: It has good initial and final adhesion to various materials such as metal, plastic, glass, sprayed surfaces, composite materials, etc.Wide temperature range: The working temperature range can usually reach -40 ℃ to 90 ℃ or even higher.Release paper/film (protective layer): High weight release paper is usually used, which is convenient for manual or die-cutting processing.2、 Main features and advantages (compared to traditional tape/glue)Excellent comprehensive performance: balancing high adhesive strength, elastic cushioning, and long-term durability.Easy and efficient construction: tear and paste immediately, no need for mixing or curing, clean and odorless, can greatly shorten assembly time and improve production efficiency.Solving complex problems: particularly adept at handling bonding scenarios with uneven surfaces, large thermal expansion differences, and vibrations.Beautiful appearance: The tape thickness is uniform, and it looks neat and tidy after installation, achieving a "seamless" installation.3、 Main types and application areasAccording to the performance focus of foam substrates and adhesives, they are mainly divided into the following categories:Universal acrylic foam tape:Features: Balancing viscosity, thickness, and cost. Foam has a medium density and good compression resilience.Application: The most common. Used for indoor and outdoor signage installation (such as acrylic letters, metal letters), decorative strip fixation, lightweight building material assembly, and household appliance bonding.VHB ® (Very High Bond) tape (a representative product of 3M, which has become synonymous with the industry):Features: Ultra high strength acrylic foam tape. Its high bonding strength can directly replace mechanical fastening methods such as rivets, screws, and spot welding in many applications, achieving "structural bonding".Applications: fixing metal panels for building curtain walls, assembling elevator cars, assembling refrigerated truck cars, bonding heavy machinery equipment panels, and installing interior parts for rail transit.Ultra thin/medium thick foam tape:Features: Thickness between 0.2mm and 1.0mm, used in situations where small gaps need to be filled and a smooth appearance is required.Application: Internal components of mobile phones/electronic products (fixing batteries, buffering FPC/PCB, filling gaps for dust prevention), film switches, medical device assembly.Flame retardant foam tape:Features: The foam substrate and adhesive have undergone special treatment and meet the UL94 V-0 flame retardant rating.Application: Places with strict fire prevention requirements, such as elevator interiors, public transportation interiors, and electrical cabinets.Thermal/conductive foam tape:Thermal conductive type: Adding thermal conductive particles to the adhesive layer or foam, used in situations that require heat dissipation and shock absorption fixation, such as the installation of certain LED modules and power devices.Conductive type: Provides electromagnetic shielding (EMI/RFI) function for grounding and shielding of electronic device enclosures.4、 How to choose and use key pointsClarify the bonding object: the most important step. Confirm that the surface energy of two materials (such as painted metal glass and plastic wall) directly affects the bonding effect.Evaluate the usage environment:Indoor or outdoor? Outdoor use must choose acrylic adhesive with excellent weather resistance.Are there any drastic temperature changes, ultraviolet radiation, humidity, or chemicals present?Is there continuous vibration or impact?Determine key performance requirements:How strong adhesive force is needed? Lightweight decoration or heavy-duty structure?How much gap do I need to fill? Select the appropriate thickness of foam based on the unevenness or tolerance of the bonding surface.Do you need any special features? Such as flame retardancy, thermal conductivity, and electrical conductivity.Surface treatment: crucial! Ensure that the adhered surface is clean, dry, free of oil, dust, and rust. The best cleaning effect is achieved using isopropanol (IPA).Construction pressure and time: After pasting, sufficient pressure (such as compacting with a roller) should be applied to ensure that the tape is in full contact with the surface. The adhesive strength will reach its maximum value over time (usually 24-72 hours).Test first: Before large-scale application, it is necessary to conduct small sample testing in real materials and environments to verify long-term reliability.5、 The core difference from PET double-sided tapeCharacteristics: Acrylic foam double-sided tape, PET double-sided tapeBase material core elastic foam (three-dimensional structure) hard polyester film (two-dimensional plane)Main functions include filling, buffering, shock absorption, and sealing, while also achieving high initial adhesion and fast bonding on a flat surface with high-strength bonding, and ensuring dimensional stabilityProficient in handling uneven surfaces, tolerances, and shock absorption scenarios, skilled in precise fitting and fixing of smooth and flat surfacesTypical thickness is relatively thick (0.2mm-3.0mm or more) and very thin (0.025mm-0.2mm)Soft to the touch, compressible and hard, incompressibleSummary: PET double-sided tape is like a "tough film", while acrylic foam tape is a "tough sponge". The former is suitable for precise and smooth "surface contact", while the latter is suitable for "body contact" in complex working conditions.summaryAcrylic foam double-sided tape is a revolutionary engineering adhesive material that solves many problems of traditional mechanical fixation and liquid adhesives in terms of shock absorption, sealing, stress management, and construction convenience through its unique "combination of rigidity and flexibility" structure. From the internal fixation of high-end smartphones to the installation of curtain walls in skyscrapers, itspresence is everywhere.Green PET tape

This is a type of pressure-sensitive adhesive tape made of polyester film (PET) as the substrate, coated with high-temperature resistant silicone adhesive, and usually made into green. Green is mainly used for visual recognition and differentiation during automatic mounting or production processes.Key features and advantagesExcellent high temperature resistance:This is its most important characteristic. The long-term temperature resistance range is usually between 130 ℃ and 200 ℃, and it can withstand peak temperatures of up to 260 ℃ or even higher in the short term (such as during wave soldering and reflow soldering).Does not melt, shrink, or residue at high temperatures.Excellent electrical insulation performance:The PET substrate itself has good insulation properties, making it suitable for situations that require insulation protection.Good chemical stability:Can resist the erosion of most solvents, acids, bases, and oils.Excellent physical performance:High strength, tear resistance, and dimensional stability (not easily stretched or deformed).The surface is flat and smooth, with no raised edges.Moderate viscosity, no residue after peeling:Silicone adhesive can maintain stable viscosity even after high temperature, and can be cleanly peeled off after cooling without contaminating the surface of the workpiece.Main application areasManufacturing of electronic circuit boards (PCBs):Wave soldering/reflow soldering shielding: During the soldering process, protect the gold fingers, connectors, or specific areas from solder contamination.PCB board splitting: During V-CUT or stamp hole splitting, fix the board edge to prevent component detachment.SMT surface mount:Perform local masking or fixation on the surface mount machine.High temperature spray painting and baking paint:In industries such as automotive and metalworking, tape is used to cover areas that do not require painting during spraying, and it can withstand high temperatures from baking.Lithium battery manufacturing:Used for processes such as fixing battery cells, protecting and insulating electrode lugs.Photovoltaic solar panels:Used for positioning and insulation in high-temperature processes such as battery cell string welding and lamination.General high-temperature bundling, fixing, and mon specification parametersColor: Green is the most common (there are also shades of tea, transparent, white, black, etc. Green is the most popular due to its light blocking and good recognition).Thickness: Common types include 25 μ m (substrate)+adhesive, 35 μ m, 50 μ m, etc. The thicker, the better the mechanical protection and insulation performance, but the flexibility will decrease.Adhesive force: usually provides moderate viscosity, but there are also high viscosity models.Length and width: shipped in rolls, with widths ranging from 1mm to 500mm or more, and lengths typically ranging from 33 meters to 66 meters.Selection and usage precautionsClear temperature requirements: Confirm the continuous operating temperature and peak temperature of your process, and select the corresponding grade of product.Testing residual adhesive: Before use, it is necessary to conduct testing under your actual workpiece material and process conditions to ensure that it can be cleanly peeled off after high-temperature cooling.Surface cleaning: The surface of the sticker must be clean and dry, free of oil stains and dust, to ensure the best bonding effect.Brand and Quality: There are numerous brands in the market with varying levels of quality.

When your application involves medium to high temperature environments and requires reliable protection and easy removal, it is usually the preferred solution.If you have more specific application scenarios (such as what products to use for and what the process temperature is), I can provide you with more targeted suggestions.Die-cutting and processing of double-sided adhesive tape
Die cutting is the process of cutting double-sided tape (or other roll like materials) into specific shapes and sizes through precision molds according to design requirements. This is a crucial post-processing step in industries such as electronics, automotive, medical, and home appliances.Below is a detailed analysis of the die-cutting process for double-sided tape:1、 Core processing flow (standard steps)Material preparation:Substrate selection: Double sided tape itself, commonly such as PET double-sided tape, foam double-sided tape, non substrate double-sided tape (film), VHB tape, etc.Release paper/film: Depending on the process requirements, it may involve single-sided or double-sided release materials.Auxiliary materials: Sometimes it is necessary to composite other materials, such as protective film, conductive cloth, insulating film, etc.Design knife mold:Types of knife molds: Commonly used are carving molds (for integral steel carving, with the highest precision), etching molds (for chemical etching, used for thin materials and complex shapes), and hardware molds (for large batches and simple shapes).Design points: Consider tape thickness, adhesion, and waste disposal methods. The blade angle and height need to be accurately calculated to ensure that the adhesive layer is cut through without damaging the backing paper or only partially cutting.Machine die-cutting:Place the raw material roll on the unwinding reel and pass it through the die-cutting machine.Driven by precision guide rails, the material passes through the die area and is cut into shape under stamping action.This is the most crucial step, which requires extremely high stability of the machine (concentricity, pressure control).Waste disposal:Frame waste removal: Remove waste edges outside the product's appearance.Inner hole waste removal: Remove unwanted adhesive material inside the product (such as the adhesive in the middle circular hole). This step is quite difficult and often requires auxiliary devices such as ejector pins and blowing air.Whether the waste disposal is clean and efficient directly determines the production efficiency and yield rate.Roll up or SMT:Roll up: Roll the die cut product back into a roll shape, usually kept on release paper.SMT: A single piece of die cut product is attached to another release film to form a single product, which is convenient for manual or automated mounting.Quality inspection and packaging:Check the size, shape, burrs, glue overflow, dirt, etc.Conducted in a clean room to prevent dust from affecting adhesive properties.Pack according to requirements for anti-static and vacuum protection.2、 Key Technologies and DifficultiesAnti overflow glue treatment:Double sided adhesive is prone to overflow due to pressure and heat, which can contaminate molds and products.Solution: Use anti overflow adhesive knife mold (special coating or structure), optimize pressure and speed, control ambient temperature, and select appropriate tape.Cutting depth control:Half cut: Only cut through the adhesive tape layer, without cutting the release paper at the bottom layer. This is the most common process with high technical plete cutting: Cut through all layers at once.Inaccurate depth control can lead to difficulty in peeling off the product or difficult waste disposal.Small size and complex shape:With the miniaturization of electronic products, the particle size may be less than 1mm and the shape may be complex (such as irregular shapes, multiple islands).Propose ultimate challenges to the precision of the cutting die, material tension control, and waste disposal technology.Multi layer composite material die-cutting:Die cutting multiple composite materials (such as tape, conductive foam, and protective film) at once, with different physical properties of each layer of material, increases the difficulty significantly.3、 Application scenario examplesMobile phones/tablets: battery mounting frame, screen pad with high foam, camera dust gasket, internal component shielding adhesive, etc.Automotive electronics: sensor fixing gasket, interior panel adhesive, wire harness fixing dical devices: disposable electrode pads, medical dressings backing adhesive, equipment sealing gaskets.Home appliances: nameplate adhesive, sealing strip, shock-absorbing gasket.4、 How to choose a suitable die-cutting supplierTechnical ability: Can you handle the complexity of your product (size, shape, material combination).Equipment level: high-precision rotary die-cutting machine or flat blade die-cutting machine? Do you have automated testing equipment?Clean environment: Whether there is a corresponding level of dust-free workshop.Quality system: Whether there is a sound ISO quality control system and whether the measuring tools are precise.Sample capability: Sampling speed and sample quality are the most direct ways to evaluate its technology.Cost and delivery time: Comprehensive evaluation while ensuring quality.summaryDie cutting double-sided tape may seem simple, but it is actually a comprehensive technology that integrates materials science, precision machinery, mold engineering, and process experience. Its value lies in transforming ordinary coils into key components that can meet specific design functions, high precision, and high reliability.If you have specific products that require die-cutting, the best way is to provide drawings or samples to a professional die-cutting factory for consultation and sampling. They can provide the most suitable process plan and quotation based on your specific needs (materials, dimensions, uses, quantities).Polyimide composite tape
Polyimide composite tape. This is an indispensable "engineering grade" high-performance tape in extreme environments and high-end applications.Core concept: Why do we need 'composite'?Ordinary polyimide tape (such as commonly known as "gold finger tape" or Kapton tape) is usually a single-layer polyimide film+single-sided organic silicone. And "composite" tape is a multifunctional and integrated solution formed by combining polyimide film with other functional materials (such as foam, fiberglass cloth, thermal conductive materials, other adhesive layers, etc.) through precision coating or bonding processes.Core concept: Combining the excellent inherent properties of polyimide (high temperature resistance, high insulation, high strength) with the complementary properties of other materials (buffering, filling, thickening, thermal conductivity) to solve complex application problems that cannot be solved by a single material.Core advantages of polyimide (PI) film (composite basis)Ultimate high temperature resistance: Long term use temperature can reach over 260 ° C, short-term can withstand high temperatures above 400 ° C, and physical properties are stable at this temperature, without melting or dripping.Excellent electrical performance: high dielectric strength, top-notch insulation material, excellent corona resistance.Excellent mechanical properties: high tensile strength, good toughness, bending resistance, and excellent dimensional stability (low coefficient of thermal expansion).Chemical stability: resistant to most organic solvents, oils, and acids.Flame retardancy: typically meets UL 94 V-0 mon Composite Structures and ApplicationsThe following are several typical polyimide composite tape structures:1. PI film+foam+adhesive layerThis is one of the most common composite structures, typically consisting of three or more layers: PI film (surface material)+adhesive+foam (intermediate layer)+adhesive+release paper.Features and advantages:PI film: provides high-strength "skin", responsible for high temperature resistance, insulation, puncture resistance, and solvent resistance.Foam (commonly used silicone foam, polyimide foam, or acrylic foam): provides cushioning and shock absorption, fills gaps, absorbs stress, compensates for tolerances, and improves sealing performance.Double sided adhesive tape: achieves firm bonding.Application Scenario:New energy vehicle battery pack: The insulation, buffering, and bonding between battery cells require insulation, fire resistance, and long-term earthquake resistance.High end motors/transformers: Insulation and fixation between coil windings must withstand high temperatures and electromagnetic vibrations.Consumer electronics: providing insulation, buffering, and certain thermal conductivity gaskets for heating elements (such as CPUs) in limited spaces.Aerospace equipment: The installation of instruments and meters requires shock absorption, insulation, and resistance to extreme temperature cycles.2. PI film+reinforcement material (such as fiberglass cloth)Composite PI film with glass fiber cloth to form an ultra-high strength composite material.Features and advantages:PI film: provides insulation and temperature resistant substrate.Fiberglass cloth: greatly enhances mechanical strength, tear resistance, dimensional stability, and puncture resistance.Application Scenario:Slot insulation and phase to phase insulation for heavy-duty motors and generators.Cable bundling that requires extremely high mechanical protection and insulation.PCB board edge reinforcement.3. PI film+thermal conductive materialComposite thermal conductive silicone or thermal phase change material on PI film to make insulating thermal conductive gasket.Features and advantages:PI film: provides electrical insulation barrier, which is a critical safety requirement.Thermal conduction layer: Conducts heat from heating elements such as IGBTs and power MOSFETs to the heat sink.Application Scenario:Power electronic module: Achieve efficient heat dissipation while ensuring high voltage insulation.Insulation and heat dissipation of heating elements in high-frequency communication equipment.4. Reinforced composite of double-sided/single-sided tapeEven as a tape, its structure may be composite. For example:Back material composite: Using PI film as the substrate for double-sided tape to provide high temperature resistance.Adhesive layer composite: using a double-layer adhesive system, such as one layer of high initial adhesive and one layer of high holding adhesive, to optimize performance.The core value brought by "composite"Functional integration: A single material simultaneously solves multiple problems such as insulation, buffering, bonding, sealing, and thermal conductivity, simplifying design and assembly.Reliability improvement: Designed for specific harsh working conditions (high temperature+vibration+high voltage), the system reliability far exceeds simply stacking multiple single materials.Space optimization: Achieve more complex functions with thinner overall thickness, saving valuable equipment space.Process simplification: reduce assembly steps, lower labor costs, and improve production efficiency.How to choose polyimide composite tape? ——Key considerationsClarify the primary and secondary contradictions: What is the main threat in your application environment? Is it high temperature, high voltage insulation, mechanical vibration, or heat dissipation? This determines the focus of the composite structure.Structural decomposition: Request specific structural layer diagrams from suppliers to understand the material, thickness, and function of each layer.PI film thickness: commonly 12.5 μ m, 25 μ m, 50 μ m, etc., determine insulation and mechanical strength.The material and density of the intermediate layer, such as the foam material (silicone, PI foam) and density (kg/m ³), directly affect the buffering and sealing performance.Adhesive type: high temperature resistant organic silicone (>200 ° C) or high-performance acrylic adhesive (lower temperature resistance but stronger adhesion)?Key performance parameters:Temperature resistance level: Long term/Short term.Flame retardant rating: UL 94 rating.Dielectric strength: kV/pression deformation: For structures with foam, this is important and affects long-term sealing performance.Thermal conductivity: For thermal conductive products.Environmental tolerance: Is it necessary to be resistant to cold and hot shock, moisture and heat aging, specific chemicals, or UV?Certification and Compliance: Material certification is crucial in fields such as automotive (such as USCAR), aviation, and rail transit.Main brands and marketsInternational leaders:3M: The product system is very comprehensive, such as a series that combines PI film and foam.Rogers: Leading in technology for high-temperature foam and composite materials.Tesa, Nitto, Saint Gobain, and others all have corresponding high-performance composite product lines.Excellent domestic suppliers:With the development of new energy and high-end manufacturing, many domestic enterprises are able to produce high-quality PI composite tapes/gaskets, especially in the field of new energy vehicle battery pack applications, where the process of localization substitution is fast.summaryPolyimide composite tape is a smart crystallization of materials engineering. It is no longer a simple adhesive or insulation material, but a systematic solution designed to cope with extreme multi physics environments. When choosing, it is necessary to start from the system requirements, communicate deeply with the supplier's R&D personnel, provide specific operating parameters, and conduct strict long-term reliability testing to ensure that this high-performance material can truly realize its "1+1>2" composite value.
