2025-11-04Green PET tape
The term 'green PET tape' may refer to several products with different functions in the field of industrial tape, and the color itself is often directly associated with its specific function, which is different from the more versatile white PET tape.Below we will provide a detailed analysis of several common green tapes, with a focus on PET material, while also clarifying other easily confused green tapes.1、 True green PET tape (functional type)This type of tape is based on PET film and dyed green to achieve specific physical functions.Green PET single-sided tape (light blocking/leak proof tape)Characteristic: This is the most common green PET tape. Green dyes can effectively absorb and block specific wavelengths of visible light, preventing light from penetrating or leaking.Main applications:Consumer electronics: widely used in the assembly of liquid crystal displays (LCDs) and bezels for mobile phones, tablets, and laptops. Used to block the light from the backlight module, prevent screen edge leakage, and improve display contrast and visual effects.Optical components: camera modules, sensors, and other components that require protection from stray light pared with white PET: White PET tape usually reflects light, while green PET tape is mainly used to absorb/block light.Green PET double-sided tapeFeatures: Apply pressure-sensitive adhesive on both sides of green PET film. It has dual functions of adhesion and light shielding.Main application: In situations where adhesion is required while strict prevention of light leakage is also necessary. For example, bonding certain components in the phone in place and ensuring that the connection does not transmit light.Other functional green PET tapesAnti static/conductive PET tape: sometimes also made green, used for electronic component packaging, coiling, or in situations where electrostatic damage needs to be prevented.2、 Other green tapes (non PET substrates) often mistakenly referred to as "PET tapes"Many green tapes on the market are not made of PET material, but they are easily confused due to their color and common uses.Green polyimide tape (Kapton tape, green version of gold tape)Substrate: Polyimide (PI), with much better high temperature resistance than PET.Color: The tape itself is usually amber (yellow gold), but the adhesive layer (acrylic or silicone) can be dyed green.Core features: Excellent high temperature resistance (long-term above 260 ℃, short-term up to 400 ℃), flame retardancy, and excellent electrical insulation.Main applications:Wave soldering and reflow soldering of electronic circuit boards: used as high-temperature protection shielding to cover gold fingers or areas that do not require soldering. This is the most classic application of green polyimide tape.High temperature spray painting and baking paint: used for high-temperature spray shielding in the automotive and aerospace industries.Important distinction: When people mention "green high-temperature tape" in electronic welding scenarios, the vast majority refer to green polyimide tape rather than PET tape.Green textured paper tapeSubstrate: Wrinkled paper coated with pressure-sensitive adhesive.Characteristics: Easy to tear, easy to peel off, moderate temperature resistance (usually 60-80 ℃).Application: Mainly used for masking during low-temperature spray painting and coating application, it is very common in decoration and car repair. Its green color may be used to distinguish different temperature resistance grades or viscosities.Green PVC electrical insulation tapeSubstrate: Polyvinyl chloride (PVC).Features: Insulation, flame retardant, wear-resistant.Application: Insulation bundling of wires and cables. This is one of the most commonly used tapes for electricians, which is completely different in material and purpose from PET tape.3、 Core Differences and Selection GuideCharacteristics: Green PET tape, Green polyimide tape, Green textured paper tape, Green PVC electrical tapeMain substrate: polyester film, polyimide film, wrinkled paper, polyvinyl chloride filmCore functions include shading, light leakage prevention, structural bonding, ultra-high temperature protection and shielding, insulation low-temperature shielding, electrical insulation protection, and bundlingModerate temperature resistance (-20 ℃~120 ℃) Extremely high (-269 ℃~260 ℃ or above) Low (usually<80 ℃) General (80 ℃~105 ℃)Typical applications include screen shading for mobile phones, soldering masking for LCD assembly circuit boards, high-temperature spray painting, coating masking, wire insulation wrappingHand feel and strength: The texture is relatively hard, the tensile strength is soft but strong, the paper is tear resistant, easy to tear, elastic, and stretchable4、 How to make the right choice?Clarify primary needs:Need to prevent light leakage? ->The preferred choice is green PET shading tape.Do you need to withstand high temperatures above 260 ℃ (such as welding)? ->Green polyimide tape must be selected.Just need regular spray paint for masking? ->Green textured paper tape is sufficient.Do you need insulated wires? ->Green PVC electrical tape.Check technical parameters: When purchasing, be sure to confirm key indicators such as product substrate (PET, PI, PVC), temperature resistance level, thickness, adhesion, etc.Testing: For critical applications, it is necessary to conduct sample testing before use to verify whether their shading effect, temperature resistance, or adhesive strength meet the requirements.summaryGreen PET tape "is a term that requires careful identification:Its core function is shading, and the main battlefield is inside consumer electronics products.Do not confuse it with the green polyimide high-temperature tape that has a similar appearance. The latter is the king of circuit board soldering protection, and their materials and temperature resistance are vastly different.If you are unsure, please prioritize the functionality (whether you want shading, high temperature resistance, or shading?), and then judge based on the usage environment, or directly provide the supplier with specific application scenarios.High viscosity PET double-sided tape
High viscosity PET double-sided tape "is a core category widely used and diverse in the adhesive industry. It combines multiple excellent performances and is a powerful assistant for precision assembly and fixing tasks.1. Core Structure and CharacteristicsAs the name suggests, it consists of three layers:Two layers: PET (polyethylene terephthalate) film. This gives the tape:Excellent dimensional stability: not easily shrink or stretch under temperature and humidity changes, ensuring adhesive accuracy.High mechanical strength: tensile, tear resistant, puncture resistant.Good chemical stability: resistant to solvents and moisture.Thinning possibility: It can achieve extremely thin (such as 0.025mm) and achieve concealed adhesion.Intermediate layer: high-performance pressure-sensitive adhesive. This is the key to achieving "high viscosity", commonly including:Acrylic adhesive: the most mainstream and has the best comprehensive performance. High transparency, good temperature and weather resistance, anti-aging (not easy to yellowing), wide viscosity adjustable range.Rubber adhesive: It has extremely strong initial adhesion and fast bonding, but is usually inferior to acrylic adhesive in terms of high temperature resistance, aging resistance, and solvent resistance.Summary of core advantages: thin thickness, high strength, strong adhesion, good temperature resistance, and easy to impact type.2. Main application scenariosWith its characteristics, it is ubiquitous in the following fields:Consumer electronics (largest application area):Fixed and buffered: batteries, screens, PCB boards in mobile phones/tablets/computers FPC、 Fixation of graphite sheets and metal shielding covers.Die cut parts: precision molded into various shapes, used for dust-proof nets, insulation gaskets, conductive foam backing adhesives, etc.Automotive Electronics and Interior:Adhesive fixation of car displays, sensors, and interior components (such as decorative strips and signs).Replace screws to achieve lightweight and vibration free assembly.Home appliances and industrial manufacturing:Assembly of control panel, glass panel, and plastic parts.Permanently attach nameplates and labels to various products.Optoelectronic display:The lamination of touch screens and the fixation of optical films.General industry and DIY: fixing small parts, temporary positioning, etc.3. Key performance parameters (must be considered when purchasing)Adhesion/Peel Strength: Measuring how "sticky" it is. The commonly used units are N/25mm or N/in. There is a distinction between "initial adhesion force" and "final adhesion force". The selection should be based on the surface material of the adhesive (such as plastic, glass, metal, painted surface).Thickness: ranging from ultra-thin 0.025mm, common 0.05mm, 0.1mm to thicker ones above 0.2mm. Thickness affects the ability to fill gaps, flexibility, and final product thickness.Temperature resistance range:Conventional type: Long term tolerance to -10 ℃~80 ℃.High temperature resistant type: using special acrylic adhesive, it can withstand -20 ℃~120 ℃ for a long time and 150 ℃ or more for a short time (such as SMT reflow soldering process).Substrate type:Transparent PET: the most versatile.White/Black PET: Provides shading, enhances aesthetics, or achieves specific visual effects.Adhesive type:Solvent based acrylic adhesive: With strong comprehensive performance, it is the mainstream.Water based acrylic adhesive: more environmentally friendly, with low VOC.Hot melt adhesive type: It sticks quickly at the beginning, but its temperature resistance is usually poor.Release paper/film: protective adhesive layer. The release force can be classified as light, medium, or heavy, which affects the ease of peeling during automatic mounting.4. Difference from VHB tape (foam double-sided tape)Often mentioned together, but with different purposes:Characteristics: High viscosity PET double-sided tape VHB tapeDense PET film with acrylic foam as the substrateCore features: ultra-thin, high-strength, high viscosity, stable size, extremely thick, high viscosity, cushioning, sealing, filling gapsThickness usually ≤ 0.2mm, usually 0.4mm~2.0mm+Main functions include precise positioning, thin pasting, insulation structure bonding, shock absorption, sound insulation, sealing, and filling uneven surfacesAnalogous application of "industrial adhesive tape" - used for fine fixation of "industrial solder joints" - used for heavy-duty bonding and sealingSimply put, PET double-sided tape is used for flat bonding that requires "thin and strong" properties; VHB is used for structural adhesives that require thickness and toughness, gaps, or buffering.5. Selection and usage suggestionsClear requirements:What material should be glued? (Surface energy is key, plastic parts are difficult to stick)What is the temperature? (SMT process must select high-temperature reflow soldering models)How thick is needed? Do you need shading?Is it permanent or removable? (There are specialized models for removable low residue adhesive)Surface treatment: Before pasting, it is necessary to clean and dry the adhered surface (wipe with IPA), which is the first and most critical step to ensure the bonding effect.Pressure and time: Apply sufficient and uniform pressure (such as rolling with a roller) after pasting, and let it stand for a period of time (usually 24-72 hours) to achieve maximum adhesion.Testing: Before conducting large-scale applications, it is necessary to conduct small-scale bonding tests and aging tests (such as high temperature and humidity, cold and hot cycles) to verify reliability.Famous brands: 3M (with highly renowned series such as 9448A and 55236), Tesa, Nitto (Nitto), Desa, Siwei, etc. They provide detailed technical parameter tables.Summary: High adhesive PET double-sided tape is an indispensable "precision bonding solution" in modern manufacturing, especially in the field of consumer electronics. When choosing, be sure to carefully match its adhesion, thickness, temperature resistance, and substrate with your specific application requirements, just like choosing precision parts.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 requirementsFlexible 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.

When making a choice, it should be systematically considered from the four dimensions of "thickness strength environment process", and fully communicated with the supplier's technical personnel to lock in the most suitable one for your product through actual testing.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.Polyimide tape

Draping precision manufacturing in golden armor: Ruili's high-temperature resistant gold finger tape in brown, safeguarding the "lifeline" of PCBsIn the high-speed electronic manufacturing workshop, every printed circuit board (PCB) carries the essence of technology and the pulse of the future. The row of golden contacts on the board, known as "gold fingers," are the lifelines for connecting signals and transmitting data. Any contamination, scratch, or solder intrusion during high-temperature soldering can lead to the failure of the entire module or even the end product.How to provide unbreakable protection for the delicate "gold finger" in this ultimate test of precision manufacturing? **Ruili Tape, with craftsmanship, presents to you - brown high-temperature resistant gold finger tape, your most trusted precision protection expert.The seemingly ordinary brown color is actually a precisely protected "golden eye"The classic brown color we chose is not a random decision. It originates from the natural color of the top-grade polyimide (PI) substrate we selected.This material is inherently endowed with extraordinary genes:Extreme temperature resistance, as stable as Mount Taishan: In harsh high-temperature environments such as wave soldering and reflow soldering at up to 280°C, Ruili gold finger tape will not melt, shrink, or deform, always fitting tightly and building a stable protective barrier for the gold finger.Excellent insulation, foolproof: With superior electrical insulation performance, it effectively prevents the risk of short circuits during soldering, ensuring the purity and safety of the circuit board.Core technology: seamless removal is the real skillThe significance of protection lies in withdrawing when the job is done. Many adhesive tapes, after being subjected to high-temperature "baking" tests, leave behind stubborn residue that contaminates gold fingers, causing poor contact and becoming the culprit that "does more harm than good".Ruili Tape is well aware of this drawback, and we have adopted a top-tier synthetic silicone adhesive system, achieving:High temperature without residue: Even after being removed under extreme heat, the gold finger surface remains as smooth and clean as new, leaving no traces, perfectly ensuring conductivity.The viscosity is just right: high initial adhesion, ensuring firm attachment and preventing warping; strong holding power, preventing displacement throughout the entire processing process; and moderate peeling force, facilitating operation and enhancing production efficiency.Flexible and tough, capable of handling complex working conditionsThe components on the PCB board are uneven, so the gold finger tape needs to have excellent flexibility and puncture resistance. The strong and tough base material of Ruili's brown gold finger tape is not easy to tear when fitting uneven surfaces, effectively resisting accidental scratches and impacts on the production line, providing comprehensive physical protection.Rilink Goldfinger Tape: Born for Efficient ManufacturingPrecision masking: It is not only suitable for gold fingers, but also for solder pads, connectors, and other areas requiring precise masking.Improve yield: fundamentally eliminate scrap and rework caused by gold finger contamination, significantly increase product pass rate, and save costs.Wide application: From consumer electronics, communication equipment to automotive electronics and industrial control, all fields involving precision welding are the stage for Ruili Tape to show its skills.Choosing Ruili is choosing peace of mind and trust.We are fully aware that on the production line where every minute counts, any minor mistake can cause huge losses.

1. What is it?Plasma spraying tape is a high-temperature masking tape. Its main function is to protect specific areas on the workpiece that do not need to be covered by the coating during plasma spraying.You can think of it as the ordinary tape and newspaper we use when painting, but it is specially designed to withstand extreme high-temperature environments.2. Main purposes and functionsSelective spraying: Ensure that the coating is only deposited on the designated functional areas of the workpiece, guaranteeing the precision and consistency of the spraying process.Protect precision parts: Protect threaded holes, bearing positions, mating surfaces, sealing surfaces, etc., to prevent coating materials from adhering to them and affecting the assembly and function of the workpiece.Form clear boundaries: At the junction where gradient coatings or different coatings are required, form neat and sharp boundary lines.3. Key features (why it is special)Due to the characteristics of plasma spraying, this tape must possess the following properties:Extremely high temperature resistance: The center temperature of the plasma jet can reach up to 10,000°C or higher. Although the surface temperature of the workpiece is controlled to be much lower, the tape still needs to withstand high temperatures ranging from 400°C to 600°C or even higher for short periods of time.Excellent ablation resistance: The adhesive and substrate of the tape cannot melt, drip, burn, or produce residues that are difficult to remove at high temperatures.Easy and clean peeling: After spraying, the tape should be easily and cleanly peeled off without leaving any residual adhesive on the surface of the workpiece. This is a key indicator to measure its quality.Good fit: It can closely adhere to surfaces with various complex shapes and roughness, preventing coating particles from infiltrating from the edges.Sufficient mechanical strength: capable of withstanding the impact of high-speed particle streams during the spraying process without being punctured or torn.Prevent spraying on the back side: Protect the side of the workpiece facing away from the spray gun from being affected by oversprayed powder.4. Common types and materialsSubstrate:Aluminum foil tape: the most common type. It utilizes the reflectivity of aluminum foil to reflect some of the heat and provides good protection and shielding effects. It usually comes with a high-temperature silicone adhesive.Glass cloth tape: made of glass fiber cloth as the substrate, coated with high-temperature silicone rubber, featuring good flexibility and high strength.Polyimide tape (also known as gold finger tape): It exhibits excellent high-temperature resistance and insulation properties, but its cost is relatively high.Adhesives: Most commonly, silicone resin adhesives are used because they maintain their viscosity at high temperatures and leave minimal residue.5. Usage ProcessSurface preparation: Clean the surface of the workpiece to ensure it is free of oil stains and dust.Shielding: According to the requirements of the engineering drawings, accurately apply high-temperature tape to the areas that need protection. For large-area protection, high-temperature shields or coatings are usually used in conjunction.Spraying: Conduct plasma spraying operations.Cooling and Peeling: After the workpiece has cooled down, carefully remove the tape. Ideally, the tape should be removed completely, leaving the protected area as smooth and pristine as before.Summary: Plasma spraying tape is an indispensable consumable in plasma spraying technology. Although it does not directly participate in the formation of the coating, it plays a crucial role in ensuring the quality, precision, and pass rate of the final product. Choosing the right tape is as important as selecting the correct spraying powder and parameters.Polyimide tape
