Detailed Introduction

<t_XXXXXX>Teflon high-temperature welding cloth, scientifically known as polytetrafluoroethylene coated glass fiber cloth, also referred to as Teflon high-temperature paint cloth, is made from a suspension of polytetrafluoroethylene (commonly called the "plastic king") emulsion impregnated onto high-performance glass fiber cloth. It is a new high-performance, multi-purpose composite material. Due to its excellent properties, it is widely used in aviation, papermaking, food, environmental protection, printing and dyeing, clothing, chemical industry, glass, medicine, electronics, insulation, construction (roof membrane structure base fabric), grinding wheel cutting, machinery, and other fields.</t_XXXXXX>
Main performance characteristics of Teflon high-temperature welding cloth:
1. It is suitable for use between -196°C and 350°C. It has weather resistance and resistance to aging. In actual applications, even after being placed at 250°C for 200 days continuously, its strength does not decrease, and its weight also remains unchanged; at 350°C for 120 hours, the weight decreases by only about 0.6%; under ultra-low temperatures of -180°C, no cracking occurs, and its original flexibility is maintained.
2. Non-adhesive: It does not easily stick to any material. It is easy to clean various oil stains, dirt marks, or other attachments on its surface; almost all adhesive substances such as paste, resin, and paint can be simply removed.
3. Resistant to chemical corrosion; can withstand corrosion from strong acids, strong alkalis, aqua regia, and various organic solvents.
4. Low friction coefficient (0.05–0.1) makes it the best choice for oil-free self-lubrication.
5. Light transmittance reaches 6～13 %.
6. It has high insulation properties (low dielectric constant: 2.6, tangent less than 0.0025), UV resistance, and anti-static properties.
7. Good dimensional stability (elongation coefficient less than 5‰) and high strength. It has excellent mechanical properties.
8. Resistant to antibiotics; non-toxic. Resistant to almost all medicinal substances.
9. Fire prevention and flame retardancy
Application Scope of Teflon High-Temperature Welding Cloth:
1. Anti-adhesion liners, gaskets, covers, and conveyor belts; depending on thickness, used for conveyor belts, adhesive tapes, sealing tapes, etc., in various drying machines.
2. Welding of plastic products, welding sealing blankets; plastic sheets, films, heat-sealing pressure sheets and backing strips.
3. High electrical insulation: electrical insulation tapes, spacers, gaskets, linings. High-frequency copper-clad boards.
4. Heat-resistant wrapping layer; layered substrate with thermal insulation wrapping.
5. Microwave pads, oven slices, food drying;
6. Adhesive tapes, transfer printing hot plates, carpet adhesive bonds and curing conveyor belts, rubber vulcanization conveyor belts, abrasive sheets and cured release cloths, etc.
7. Pressure-sensitive adhesive tape base material.
8. Building membrane materials: Canopies for various sports venues, station pavilions, umbrellas, landscape canopies, etc.
9. Corrosion-resistant coatings for various petrochemical pipelines, and environmental desulfurization for power plant exhaust gases, etc.
10. Flexible compensator, friction material, grinding wheel slices.
1.1 After special processing, “anti-static fabric” can be produced.
Main varieties and specifications of Teflon high-temperature welding cloth:
Thickness: 0.06–1.0 mm.
Stitching pattern: plain, twill, satin, etc. Width: 1000–4200 mm.
Colors: brown, white, black, black-silver, pink.
Coating methods: double-sided coating, single-sided coating, breathable coating, anti-static coating.
Notes:
According to different application requirements, we can produce Teflon heat-resistant welding blankets of various grades, such as:
1. General industrial grade: This grade of fabric possesses excellent heat resistance, anti-corrosion properties, and non-stick characteristics, and is primarily used in various industrial fields.
2. Standard grade: Produced from materials that not only possess excellent anti-corrosion and heat resistance properties, but also have a smooth, flat surface with low stickiness. It can be used in general industrial applications, and offers advantages when used for plastic demolding or as separators, gaskets, and demolding surfaces for various products.
3. Food-grade: Smooth and flat surface, good anti-stick properties, resistant to heat, easy to clean, and safer for use in the food industry.
4. Anti-static grade (anti-static fabric): In addition to the traditional properties of Teflon glass fiber fabric, it is processed using special techniques to enhance anti-static capabilities, meeting specific customer requirements.
