Ceramic backing tape "is a broad term that encompasses a variety of products. According to the core application scenarios, it can be mainly divided into two categories: welding special gaskets and high-temperature resistant insulation/fireproof tapes.👉 Welding Ceramic backing tapeThis is the most common term for "ceramic backing tape", mainly used for single-sided welding and double-sided forming processes.Core working principle: During welding, it is attached to the back of the weld seam to support the molten metal, prevent it from dripping, ensure that the root of the weld seam is completely melted, and achieve one-time molding and aesthetic appearance of the back. Essentially, it is a process auxiliary material for single-sided welding and double-sided forming.Main application areas: shipbuilding (hull outer panels, decks), bridge construction, boiler and pressure vessel manufacturing, steel structure construction, pipeline engineering, etc.Material composition: It is mainly composed of natural inorganic materials such as alpha alumina (α - Al ₂ O3) and kaolin, which are sintered at high temperatures of 1350-1400 ℃. Some products are pasted on aluminum foil tape for construction purposes.Performance characteristics:High temperature resistance: The fire resistance usually exceeds 1300 ℃, and some materials can withstand high temperatures above 1500 ℃.Chemical stability: resistant to acid, alkali, and chemical corrosion, will not react with the molten metal during welding, ensuring the purity of the weld seam.Good thermal stability: With a low coefficient of thermal expansion, it can effectively resist the thermal shock of rapid heating and cooling.🛡️ High temperature resistant insulation/fireproof tapeThis type of tape is not designed for welding processes, but utilizes the fire-resistant, insulating, and heat-insulating properties of ceramic materials to provide protection for equipment or places.Main types:Ceramic Fiber Tape: Woven from ceramic fiber yarn, used as insulation, sealing, and insulation material in high-temperature areas, such as pipe wrapping, furnace door sealing, etc.Ceramic Silicone Tape: Soft and elastic at room temperature, it will quickly sinter into a hard ceramic shaped protective shell when exposed to high temperatures (such as fire), providing fire and fire-resistant effects. The fire-resistant layer commonly used for fire-resistant cables.Main application areas:Sealing and insulation of high-temperature pipelines, flanges, valves, and furnace doors.Fire prevention, fire resistance, and insulation wrapping of wires and cables.Pads and isolation protection for high-temperature areas of equipment.Glass fixed sealing for fire doors.Performance characteristics:High temperature resistance: Ceramic fiber tape can withstand high temperatures of about 1260 ℃; Ceramic silicone rubber tape can form a protective shell under flames.Electrical insulation: These products, especially ceramic fibers and ceramicized silicone rubber tapes, typically have excellent electrical insulation properties.Chemical corrosion resistance: able to resist the erosion of most chemicals and solventsHow to choose and use?Clarify core requirements: First, determine whether you want to solve welding process problems or require high-temperature sealing or fire prevention.Precise product selection: Choose corresponding products according to different needs.Verify key parameters: Carefully verify the product's temperature resistance level, size specifications, and certification (such as CCS/ABS certification from classification societies).Pay attention to construction details:For adhesive welding pads, ensure a tight fit and avoid air bubbles.Ceramic fiber products can usually be cut with ordinary scissors. Some products should be noted that slight smoking or blackening may occur during the first high-temperature heating, which is a normal phenomenon.For pressure-sensitive ceramic tape, additional mechanical fastening may be required when the application temperature exceeds approximately 204 ° C (400 ° F)Die casting demolding anti scratch and high temperature protection PTFE tape
PTFE tape is indeed a fairly mature industrial solution for the challenges you encounter in demolding, workpiece scratches, and high-temperature environments during die-casting processes.It essentially combines the non stick properties of polytetrafluoroethylene (PTFE) with the convenience of adhesive tape, forming a smooth and high-temperature resistant "physical barrier" directly on the surface of the mold.🔑 Core Performance: Why is it capable?The reason why it is suitable for die-casting demolding mainly depends on the following performance:Excellent high temperature resistance: This is a basic requirement. High quality PTFE tape can be continuously used in the temperature range of -70 ℃ to+260 ℃, and some products can withstand high temperatures of up to 300 ℃ in the short term, which can stably cope with the high heat environment during the die-casting process.Smooth and extremely low friction coefficient: Its surface is very smooth and almost does not adhere to any substances (such as molten plastic, resin, etc.), ensuring smooth demolding of castings and effectively avoiding scratches.Excellent mechanical strength and durability:Scratch resistant: Teflon itself has a certain degree of hardness and wear resistance, but the mechanical strength of the tape depends more on its substrate.For die-casting scenarios, it is recommended to choose reinforced adhesive tape based on glass fiber (commonly known as "fiberglass cloth base"), which has high tensile strength and can better resist the impact of molten metal flow and the wear of mold closure, thereby achieving reusability and reducing maintenance costs.Widely resistant to chemical corrosion: It is almost not corroded by any strong acid, strong alkali, or organic solvent, and can adapt to various release agents or oil stains that may exist in the die-casting environment.Cleanliness and residue free: After high-quality silicone pressure-sensitive adhesive is peeled off at high temperatures, the back of the tape will not leave stubborn residue on the surface of the mold being bonded, which helps to keep the mold clean.High insulation performance: Teflon tape also has excellent electrical insulation performance, with some models having a breakdown voltage of up to 25KV, providing additional protection in scenarios that require electrical isolationSelection and usage suggestionsTo select the most suitable adhesive tape for your die-casting process, you can focus on the following aspects:Clear usage requirementsTemperature and pressure: Confirm the working temperature and pressure that the mold is subjected to.Wear resistance requirements: Based on the mold structure and working conditions, evaluate the requirements for the wear resistance of the tape, and decide whether to choose pure PTFE film (with good flexibility, suitable for complex surfaces) or fiberglass cloth based reinforced type (with high strength and more wear resistance).Thickness and size: Select the appropriate thickness (such as 0.08mm, 0.13mm, 0.25mm, etc.) based on the precision requirements of the mold, and confirm whether a specific width or customized shape is needed.Focus on key parametersMaximum operating temperature: Ensure that the upper temperature limit of the tape is higher than your process temperature.Tensile strength: This is particularly important for fiberglass cloth tape, as it directly affects its durability.Adhesive strength: The peeling force on steel is one of the key indicators, for example, 3M 5498 has a peeling force of about 22-48N/100mm on steel.Thickness range: The thicker the thickness, the better the strength and durability.Proper installation and maintenanceThoroughly clean: Before pasting, be sure to thoroughly clean the surface of the mold with a suitable solvent (such as acetone) to ensure that there are no oil stains or impurities, in order to ensure optimal adhesion.Smooth pasting: When pasting, avoid generating bubbles and use a scraper to smooth from the center to the edges.Regular inspection: Regularly check the wear of the tape during production intervals. Once serious scratches or peeling are found on the surface, it should be replaced in a timely manner.Easy replacement: After tearing off the old tape, if there is any residue, it can be removed with alcohol or a special cleaning agent, and then a new tape can be reattached.There are many manufacturers and brands on the market that supply PTFE tape. We suggest that you evaluate from these perspectives in order to find the most suitable "invisible protector" for your die-casting conditions.Friction resistant PTFE high-temperature cloth tape mold compression protection
Friction resistant PTFE high-temperature cloth tape is an industrial tape that combines the excellent non adhesiveness of PTFE with the high strength of glass fiber cloth. It is designed specifically for anti sticking, insulation, and wear resistance requirements in high temperature, high pressure, and high wear environments.It is commonly referred to as PTFE high-temperature tape or PTFE fiberglass tape, made by coating PTFE on fiberglass cloth. Compared with ordinary PTFE film tape, its core characteristics emphasize more on mechanical strength and wear resistance.Core technical parametersFor your convenience in evaluation, the following are the key performance indicators and common specifications of this type of tape:Characteristic Typical Parameters/Specification DescriptionLong term temperature resistance: -70 ℃ to 260 ℃Short term: can reach 280 ℃ -300 ℃ and maintain stability in a wide temperature range, suitable for high temperature conditions.Wear resistant composite glass fiber cloth with high tensile strength (such as 900 N/100mm) is the outstanding advantage of this type of tape. Fiberglass base fabric provides excellent mechanical strength and tear resistance, making it more durable in friction and scratch environments.The extremely low friction coefficient of 0.05-0.1 gives it excellent "non stick" properties, which can effectively prevent material adhesion and assist in sliding.Excellent anti adhesion performance, PTFE coating surface hardly adheres to any substances, including glue, resin, oil stains, etc., making it easy to clean.Excellent corrosion resistance, able to resist corrosion from strong acids, strong bases, and various organic solvents, with high chemical stability.High electrical insulation and dielectric constant<2.6 can be applied in scenarios that require electrical insulation protection.The conventional thickness of 0.08mm to 0.5mm is a key parameter affecting wear resistance and service life, which can be selected according to the application mon colors: brown, black, white, blueOther features include fire resistance, flame retardancy, UV protection, and anti-static. Some products also have these additional functions to adapt to more special environments.Main application areasBased on its characteristics of wear resistance, high temperature resistance, and anti sticking, it is mainly applied in the following scenarios:Packaging and heat sealing industry: used for hot pressing sealing end faces of bag making machines and sealing machines to prevent the packaging film from melting and sticking to the heating block, ensuring sealing quality and production efficiency.Industrial rollers and drying drums: Covering the surface of drying drums in papermaking, printing and dyeing, bonding and other equipment to prevent material adhesion and protect the drum surface from wear and tear.Electronic and electrical insulation: As an H-grade (above 180 ℃) temperature resistant insulation material, it is used for wrapping and insulation protection of coils and cables.Thermoplastic mold demolding: The liner is placed on the mold or heating plate as a demolding medium, making it easy for the formed plastic or composite products to detach without the need for demolding agents.Chemical anti-corrosion lining: used as an anti-corrosion and wear-resistant lining for chemical pipelines, reaction vessels, hoppers and other equipment to protect the equipment substrate.Aerospace: Can be used as a liner for aerospace molds to meet the high temperature and high-precision demolding requirements.Main brands and market reference pricesThere are multiple brands in the market that offer this type of product, and the following are reference information from several mainstream manufacturers:Typical brand models/series reference prices (example) Remarks3M 3M ™ PTFE 5451 and 5453 are internationally renowned brands with high prices (usually measured by roll), stable performance, and offer a variety of width and length specifications.Tesa (tesa) tesa ® 4800 is a high-performance adhesive tape designed by Desha specifically for demolding applications, with a relatively high price (usually calculated by roll), emphasizing mechanical stability and wear resistance.NITTO (Nitto) No.903UL, No.973UL approximately ¥ 143/roll (10m long) is a Japanese brand with a high market share and a rich product line, offering a variety of widths and thicknesses to choose from.Domestic manufacturers such as Qiaorui, Giant Adhesive Tape, and SKF offer high cost-effectiveness at around ¥ 10-35 per roll (10m in length) and flexible customization of specifications, making them widely used in the domestic industrial market.Summary: Friction resistant PTFE high-temperature cloth tape is an industrial tape that integrates multiple properties such as high temperature resistance, wear resistance, anti sticking, and insulation. It is an effective solution to solve the problems of material adhesion and wear under high temperature conditionsThermal anti adhesive protective film
Thermal anti adhesive protective film is a functional thin film material that can significantly reduce or even eliminate its viscosity by heating, thereby achieving no residual adhesive and no damage peeling.Its core lies in a "thermal response" mechanism. Simply put, before heating, it can provide sufficient adhesion to fix and protect the workpiece, just like a regular protective film; After the process is completed, simply heat it to a specific temperature, and the viscosity will sharply decrease (from a few hundred grams of adhesive force to negligible), making it easy and clean to peel off.1、 Core principle: Two mainstream technological routesThere are two main technologies for achieving this "thermal anti sticking" effect, which are currently applied in the market:Foaming type: using microsphere expansion to break the bondThe adhesive layer of this protective film is dispersed with tiny thermal expansion microspheres. After heating, the microspheres rapidly expand and increase in volume, disrupting the continuity of the adhesive layer and causing a sharp decrease in the contact area between the adhesive layer and the surface of the object being adhered, resulting in loss of adhesion.Key indicators: Heating expansion to lose viscosity usually takes only 10 seconds to 5 minutes, depending on the heating temperature and the formula design of the protective film.Peeling effect: It can achieve "automatic peeling", that is, after heating, the adhesive film will automatically arch or fall off from the surface of the workpiece due to the loss of viscosity, greatly improving efficiency.Material phase change type: using special polymer materialsThis is a relatively new technology that does not use foaming agents. It is achieved by adding a specific proportion of liquid crystal material (such as 5% -15% of the total weight) to the acrylic resin adhesive chanism of action: At room temperature, the liquid crystal molecules in the adhesive layer maintain an ordered state, providing high viscosity; After heating, the liquid crystal molecular structure undergoes a thermally induced phase transition, breaking the molecular arrangement of the adhesive and resulting in a significant decrease in its macroscopic adhesion.Advantage: This design can avoid the residual glue problem that may exist in traditional heat reducing films and improve the reliability of peeling.2、 Key characteristics and important parametersWhen choosing a thermal anti adhesive protective film, the main focus is on the following core parameters:Typical numerical range of parameters/explanation of impact and selection suggestionsPeel off temperature low temperature: 90-100 ° CMedium temperature: 120-130 ° CHigh temperature: The core indicator selected is 140-180 ° C. It must be higher than the process temperature during processing, but it cannot be too high to avoid damaging the workpiece that is not heat-resistant.Initial viscosity low viscosity (~200g/25mm)Medium viscosity (~400g/25mm)High viscosity (~700-1500g/25mm) is selected based on the weight of the workpiece and fixing requirements. Excessive adhesion may cause difficulty in peeling off after processing, while insufficient adhesion may prevent firm fixation.After heating, the viscosity usually drops to<10g/25mm, or even lower to 0.02N/20mm, which is the key to evaluating the difficulty of peeling. The smaller the value, the easier the peeling and the lower the risk of damage to the workpiece.The common substrate and thickness are PET (polyester film), as well as high-temperature resistant materials such as PI. The total thickness is usually between 50 μ m and 115 μ m. PET has good comprehensive performance and low cost; PI has better heat resistance. Thickness affects flexibility and strength, and needs to be adapted to the surface and processing method of the workpiece.The core advantage of this product is to have no residual adhesive after peeling, but the compatibility between the product and specific materials needs to be verified in application.3、 Main application areasThanks to its heating and anti sticking properties, thermal anti sticking protective films are widely used in precision manufacturing fields that require temporary fixation and protection, especially in the electronics industry:Semiconductors and Microelectronics: Used for fixing and protecting the backside grinding and cutting process of chip wafers. After cutting, heating can easily pick up individual chips (grains) from the tape without damaging the chips or leaving adhesive residue.Passive component manufacturing: used for cutting, positioning, and handling in the manufacturing process of small components such as MLCC (Multi Layer Ceramic Capacitor) and MLCI (Chip Inductor).Optoelectronics and flat panel displays: used for protection during the thinning, grinding, and polishing processes of LCD/TP touch panel glass.New material processing: used as a temporary carrier and protective layer in the transfer printing process of materials such as graphene and carbon nanotubes.Other applications: including but not limited to cutting and grinding of LED chips, precision metal component processing, ceramic substrate cutting, etcBright black (matte black) polyester film
Bright black (matte black) polyester film is a common functional PET film in industry, characterized by excellent light shielding and mechanical and electrical insulation properties.

Using glass cloth tape to stick silicone rubber, common application scenarios include using it as an auxiliary material in FPC (flexible printed circuit board) lamination process, or fixing and protecting silicone components in high temperature environments.Here is a detailed operation guide, hoping to be helpful to you:✍️ preparation in advanceSurface cleaning: This is the most crucial first step. Please use a dry cloth, brush, or dipped in alcohol, acetone, or other cleaning agents to thoroughly remove dust, oil, and impurities from the silicone rubber and the surface of the object being pasted, to ensure a firm adhesion and avoid moisture affecting electronic products during cleaning.Material cutting: Cut the glass cloth tape and silicone rubber into suitable shapes and sizes according to actual needs.📝 Paste core stepsPositioning and pasting: Due to the strong initial adhesion of the glass cloth tape, it is difficult to adjust once it is pasted, so it is necessary to accurately paste it all at once after determining the position. Use the "direct bonding method" to attach the tape to the silicone rubber, and repeatedly press the tape with force to fully utilize the adhesive layer, ensuring no bubbles and tight pression and static placement: In specific processes such as FPC compression, hot pressing is usually required after bonding. Accurate control of parameters such as pressure, temperature, and time is required. After completing the operation, it is best to let it stand for 24 hours to achieve the best bonding strength of the tape, and try to avoid applying external forces to the bonding area during this period.Surface protection and inspection: After pasting, if there is glue overflow, it can be carefully cleaned with a blade. The final step is to carefully check whether the adhesive surface is smooth and free of impurities such as bubbles and particles, to ensure the quality of the bonding.Here are several typical application scenarios that can be referred to:💡 Application scenario referenceFPC hot pressing process: The glass cloth tape is attached to the silicone rubber, which plays a role in buffering, preventing displacement, blocking adhesive overflow, and filling uneven lines during pressing.High temperature equipment fixation: Utilizing its wide temperature resistance range of -40 ℃ to 260 ℃, it is used for sealing, sandblasting protection, coil binding, etc. of high-temperature pipelines.Adhesive of silicone related products: Some special tapes (such as Japan's IPROS G-301 and Desha's 61526) can directly adhere silicone or perform heterogeneous bonding between silicone and other materials.Temporary protection and fixation: used to shield and protect specific parts of precision electronics or household appliances during painting, welding, and other processes, with no residual adhesive after removal
