Polyimide film (PI) tape is a high-performance high-temperature tape made from polyimide film as the tape material. Its main uses are heat-resistant shielding and heat-resistant insulation for electronic boards.Due to the high thermal decomposition temperature of polyimide, it has excellent heat resistance and insulation performance. Many polyimide tape products use silicone adhesives, which have the advantage of leaving no residue even after being removed. Polyimide (PI) film tape not only features high-temperature resistance, chemical corrosion resistance, good insulation, and super strong adhesion, but also possesses other excellent properties such as radiation resistance, flame retardancy, wear resistance, and anti-corrosion. Polyimide (PI) tape can be classified into two types based on the adhesive used: PI silicone tape and PI acrylic tape. In terms of appearance, it is generally available in two colors: brown and black. Product Features:High temperature resistance: Polyimide film tape has good high temperature resistance and can withstand temperatures up to 400 ℃.Chemical corrosion resistance: Polyimide film tape is not easily corroded by chemical substances and has strong corrosion resistance.Good insulation: Polyimide film tape has excellent insulation performance and can effectively protect electrical equipment.Super strong adhesion: Polyimide film tape has strong adhesion and can firmly fix objects without deformation or damage at high temperatures.Anti corrosion: Polyimide film tape has excellent anti-corrosion performance, which can prevent rusting of metal materials such as steel.Product application:PI silicone tape is mainly used for applications that require high temperature resistance or high initial adhesion, such as insulation wrapping of H-grade motor and transformer coils, fixing and wrapping of high temperature resistant coil ends, thermal resistance protection for thermometers, insulation for capacitors and wire entanglement and other bonding under high temperature working conditions, temperature protection for PCB sheet metal fingers and electronic components during SMT, external wrapping of polymer lithium batteries, etc.PI acrylic tape is commonly used for insulation protection of PCB boards, fixing and wrapping of wire harnesses, interlayer and outer wrapping of transformer coils, external insulation of lithium batteries, etc.Characteristics of PolyimidePolyimide is a general term for polymer compounds polymerized by imide bonds, but the material used for polyimide tape is aromatic polyimide, which is made of aromatic compounds polymerized by imide bonds.Due to its strong adhesive strength, it has high strength, heat resistance, and insulation properties. The thermal decomposition temperature exceeds 500 ℃.The specific characteristics of the molecular structure that endow it with excellent heat resistance are as follows:Aromatic compounds have conjugated structures through imide bonds.Due to the aromatic rings being located on the same plane, the molecular chains are tightly packed together.Highly polar imide bonds have strong intermolecular forces.In addition, the coefficient of expansion during heating is relatively low, so even when used at high temperatures, it will not expand too much, thereby reducing dimensional errors.Understand one article!

When choosing high-temperature resistant tape suitable for your industry, you need to consider the following key factors to ensure that the selected tape can meet the specific needs of the industry: Temperature tolerance: Determine the required temperature tolerance based on the industry application environment. The working temperature range varies greatly among different industries, so when choosing high-temperature adhesive tape, the first step is to determine the maximum temperature that the tape can withstand. Generally speaking, the temperature range that high-temperature adhesive tape can withstand is between -40 ℃ and 1000 ℃, but the specific range depends on the type and brand of the tape. Material characteristics: Select adhesive tape with specific material properties according to industry requirements. For example, certain industries may require tape to have good chemical or corrosion resistance. Common high-temperature resistant tape materials include polyimide, silicone, glass fiber, and fluoroplastics, each of which has different characteristics such as heat resistance, insulation, corrosion resistance, etc. viscosity: Ensure that the selected tape can firmly adhere to the desired surface and remain stable in high temperature environments. Choose tape with strong adhesion and high temperature resistance to ensure that it does not lose its adhesion at high temperatures. Size: Choose the appropriate tape width and length based on specific application requirements. Different industries and application scenarios may require different sizes of tape, so it is necessary to choose according to the actual situation. Additional features: Choose the appropriate tape width and length based on specific application requirements. Different industries and application scenarios may require different sizes of tape, so it is necessary to choose according to the actual situation. In summary, choosing a high-temperature resistant tape suitable for one’s own industry requires consideration of multiple factors such as temperature tolerance, material properties, viscosity, size, and additional characteristics. By considering these factors comprehensively, one can choose the most suitable high-temperature resistant tape for their industry needs.Anti static PI tape
Anti static PI tape is a functional tape made of polyimide (PI) film substrate, which has the ability to discharge static electricity through a special process. It combines the excellent high temperature resistance and anti-static (ESD) properties of PI materials, and is mainly used in high-temperature processes such as electronic manufacturing that are sensitive to static electricity.🔬 Core feature: Combination of high temperature resistance and anti-static propertiesCompared with ordinary PI tape (gold finger tape), its core difference lies in its electrical properties: ordinary PI tape is an excellent insulator and is prone to accumulating static electricity; And the anti-static PI tape can safely discharge static charges through modification.Its main characteristics include:Anti static performance: This is the core function. Its surface resistance is usually controlled within the dissipative range of 10 ⁵ -10 ⁹ Ω, which can effectively discharge electrostatic charges and avoid damaging sensitive components. High quality adhesive tape also strictly controls the peeling voltage, for example, when peeled off from the surface of a golden finger, the voltage generated can be lower than 50V, far lower than the tens of thousands of volts that ordinary PI tape may generate.Excellent high temperature resistance: Inheriting the genes of PI materials, it can withstand short-term peak temperatures of 260 ° C or even higher, which is sufficient to cope with lead-free soldering processes. Long term use can also reach temperatures above 200 ° C. It should be noted that the heat resistance of the adhesive layer is usually lower than that of the substrate, and the failure of the adhesive layer at high temperatures is the main cause of detachment.No residue and clean peeling: After high-temperature processing, the tape needs to be able to be cleanly peeled off, leaving no residue on the protected surface (such as gold fingers), which is crucial for ensuring the reliability of subsequent welding and electrical connections.Other physical properties: typically possessing high tensile strength (such as 3M 5419 up to 578 N/100mm), excellent resistance to chemical solvents, and flame retardancy to meet the requirements of complex process environments.📊 Key technical parameter referenceThe product parameters of different manufacturers may vary, and the following are typical ranges for your reference when selecting:Typical specifications/ranges of parameter itemsSubstrate polyimide (PI) filmAdhesive: Organic silicon pressure-sensitive adhesive or acrylic adhesiveTotal thickness 0.06mm-0.07mm (common)Color: Tea/Amber/GoldStandard width can be customized for slitting (commonly 3mm -500mm)Standard length 33m (most common)Surface resistance 10 ⁵ -10 ⁹ Ω (dissipative type)Stripping voltage ≤ 50V or ≤ 150V (depending on the product)Long term temperature resistance above 200 ° CShort term temperature resistance of 260 ° C to 280 ° C🏭 Main application areasIts core application scenario is to provide temporary protection for electrostatic sensitive areas in high-temperature processes.Golden finger protection in PCB manufacturing: This is the most classic application. During the process of wave soldering and reflow soldering, the gold fingers (connecting contacts) used to shield and protect the PCB board prevent contamination from soldering and plating solutions, and do not damage components due to static electricity when removed.SMT surface mount technology: used to protect sensitive components on circuit boards from damage caused by electrostatic discharge (ESD) during high temperature and operation.Electronic component manufacturing process: suitable for insulation wrapping, fixing, and shielding that require high temperature resistance and anti-static properties, such as transformers, relays, motor coils, etc.New energy and lithium batteries: In lithium battery manufacturing, they can be used in fixed or insulated scenarios that require flame retardancy and anti-static.📝 How to choose: key considerationsWhen selecting, it is recommended to confirm the requirements according to the following priority:Confirm the anti-static level: Firstly, clarify the surface resistance range required for the application. Do we only need dissipative type (10 ⁵ -10 ⁹ Ω) or conductive type (lower resistance)? Request third-party testing report confirmation.Match temperature resistance curve: distinguish between short-term peak temperature (such as 260 ° C for wave soldering) and long-term operating temperature. Ensure that the temperature resistance level of the tape covers your entire process window.Verification of stripping voltage: For protecting sensitive components such as gold fingers, stripping voltage is a key indicator. Request the supplier to provide this data to ensure that it is sufficiently low (e.g.<50V) and will not cause ESD damage.Confirm no residual adhesive performance: Especially after high-temperature processes, it is necessary to ensure that the tape can be cleanly peeled off. Suppliers can be requested to provide actual application cases or test reports.Pay attention to environmental compliance: For exported products or high-end applications, it is necessary to confirm whether the product meets environmental regulations such as ROHS and REACHFlame retardant cotton paper double-sided tape
Flame retardant cotton paper double-sided tape is a functional double-sided tape made of flame retardant cotton paper as the substrate and coated with flame retardant adhesive on both sides. Its core value lies in providing reliable bonding while effectively preventing flame spread, making it suitable for scenarios with safety regulations.🔬 Core feature: More than just 'stickiness'Compared with ordinary double-sided tape, its key difference lies in its flame retardant ability of self extinguishing upon ignition, which is usually reflected through UL94 VTM-0 or V-0 level certification. Its main characteristics include:Flame retardant and fire-resistant: The flame retardant rating can reach UL94 VTM-0 (for thin materials) or V-0, and often meets the environmental requirements of halogen-free, low smoke, and non dripping combustion.Adhesive performance: It has good adhesion to various materials such as foam, plastic, and metal, with both high initial adhesion and holding strength.Temperature resistance and weather resistance: It has excellent temperature resistance, with long-term temperature resistance usually ranging from 80 ° C to 120 ° C, and short-term tolerance ranging from 150 ° C to 180 ° C. At the same time, it has good solvent resistance and UV resistance.Processing and Environmental Protection: Easy to die cut and most products comply with environmental regulations such as ROHS and REACH.📊 Common technical parameter referenceThe product parameters of different manufacturers may vary, and the following are typical ranges for your reference when selecting:Typical specifications/ranges of parameter itemsBase material flame-retardant cotton paperAdhesive acrylic ester (with added flame retardant)Total thickness 0.09mm-0.5mm (commonly 0.1mm, 0.12mm, 0.15mm)Color semi transparent, milky whiteStandard width 1000mm -1240mm (customizable for slitting)Standard length 50m, 100m, 200mLong term temperature resistance of 80 ° C-120 ° CShort term temperature resistance of 100 ° C to 180 ° CFlame retardant grade UL94 VTM-0/V-0🏭 Main application areasWith its dual characteristics of flame retardancy and adhesion, it is widely used in multiple industries that require safety:Electronic appliances: used for coil wrapping and insulation fixation of transformers, motors, relays, cables, as well as battery insulation and bonding of internal components of electrical appliances.Automotive industry: used for fixing automotive interior parts, such as the bonding of signs and decorative strips, and also for flame retardant bonding scenarios such as automotive PACK (battery pack).New energy and lithium batteries: In the manufacturing of lithium batteries, they are used to adhere to foam, play a fixed role in flame retardancy and fire prevention, and meet strict supply chain safety audits.Architecture and Transportation: Can be used for the bonding of indoor building materials, as well as the pasting of interior decorative materials such as train carriages and airplanes.Other industries: suitable for pasting nameplates, film switches, and bonding foam and rubber materials that require flame retardancy.📝 How to choose: key considerationsWhen making a selection, it is recommended to confirm the requirements according to the following steps:Confirm flame retardant level: Firstly, clarify the flame retardant standard required for the application scenario, whether it is UL94 VTM-0 (thin material) or V-0 (thicker material), and request a third-party testing report.Matching temperature resistance requirements: distinguish between long-term use temperature and short-term peak temperature. For scenarios such as electronic appliances and car interiors, conventional cotton paper substrates can be selected for long-term temperatures ≤ 100 ℃; If high-temperature structural bonding is involved, higher performance substrates (such as PET, PI) or specialized products need to be considered.Determine thickness and viscosity: Choose the thickness based on the surface roughness and gap size of the adhered material. Generally, thicker adhesive tape has better adaptability to rough surfaces, but it is necessary to balance its flexibility with the final bonding strength.Pay attention to environmental compliance: For exported products or high-end applications, it is necessary to confirm whether the product meets the requirements of halogen-free, ROHS, REACH and other environmental regulationsPlasma spraying high-temperature adhesive tape
Plasma spray high-temperature tape, more accurately referred to as thermal spray masking tape in the industry. It is a critical consumable used to protect non spray areas of workpieces in extreme processes such as plasma spraying, flame spraying, HVOF (supersonic flame spraying), or sandblasting.🧬 Core Composition and Working PrincipleThis type of tape is usually made of high-strength glass fiber cloth or silicone rubber as the substrate, coated with high-temperature special silicone adhesive. Its working principle is to adhere to the surface to be protected before spraying, utilizing the high-temperature, wear-resistant, and impact resistant properties of the substrate to resist high-speed splashing molten particles and high-temperature flames. After spraying is completed, it can be cleanly peeled off without leaving any residual adhesive.🎯 Key performance indicatorsWhen choosing this type of tape, it is important to pay attention to the following core parameters:Temperature resistance range: The continuous working temperature of mainstream products can usually reach 260 ° C (500 ° F). Some products designed for special working conditions, such as Dalian Yibang's CYB0511 series, can withstand short-term high temperatures of 300-600 ° C and support multiple spray applications.Wear resistance and impact resistance: It must be able to withstand the strong abrasion of sandblasting pretreatment before spraying, and not be damaged or delaminated under high pressure and high-speed particle impact.Adhesion and peel performance: Strong adhesion is required at high temperatures to ensure no displacement or edge warping on complex curved or vertical surfaces; At the same time, after spraying is completed, it should be able to be cleanly peeled off without leaving any residual adhesive.Physical flexibility: Excellent tape should be able to tightly adhere to complex geometric shapes, such as blade tenons, curved surfaces, etc., providing seamless shielding.Insulation and flame retardancy: As industrial protective materials, good insulation performance and flame retardancy are usually required to enhance operational safetyHow to choose and useKey selection points:Check temperature: For regular spraying, choose products with a temperature rating of 260 ° C; If it involves high-temperature alloys or long-term operations, it is necessary to choose models with higher temperature resistance.Wear and tear: only anti spray can choose the standard type; If strong sandblasting is required, green or high wear resistant series should be selected.Look at the shape: For complex surfaces, choose thinner and more flexible single-layer tape, such as DeWAL Plasma X.Judging from the process: The particle velocity and impact force of HVOF process are extremely strong, so it is necessary to choose tape specifically optimized for HVOF.Usage suggestion:Surface cleaning: Before pasting, ensure that the surface of the workpiece is dry and free of oil stains to ensure optimal adhesion.Fully compact: After pasting, press firmly, especially at the edges, to avoid molten particles from infiltrating from the edges during spraying.Multi layer protection: Under extremely harsh spraying conditions, it may be considered to stick multiple layers of tape to provide more reliable protection.Timely removal: After spraying is completed, it is recommended to remove the tape before the workpiece is completely cooled. At this time, the tape still has some flexibility and is easier to clean and peel off.High temperature resistant white glass cloth tape
