General industrial grade PTFE coated fiberglass brown fabric

General industrial grade PTFE coated fiberglass brown fabric

The PTFE coated woven fiberglass membrane name PTFE coated fiberglass fabric, also known as PTFE high temperature varnish fabric, is a suspension of polytetrafluoroethylene (commonly known as plastic king) emulsion as raw material, impregnated with high performance glass fiber cloth. It is a new product with high performance and versatile composite materials. Because of its excellent performance, it is widely used in aviation, paper, food, environmental protection, printing and dyeing, clothing, chemical, glass, medicine, electronics, insulation, construction (shelf film structure base fabric), grinding wheel slicing, machinery, etc. field.

Main performance characteristics of General industrial grade PTFE coated fiberglass brown fabric:

1. Good dimensional stability (extension coefficient less than 5‰) and high strength. Has good mechanical properties.

2. Used for low temperature -70 ° C, high temperature 260 ° C, with weather resistance, anti-aging. After practical application, if placed continuously for 200 days at a high temperature of 250 °C, not only the strength will not become lower, but also the weight will not decrease; when placed at 350 ° C for 120 hours, the weight will only decrease by about 0.6%; at -180 ° C No cracks occur at ultra-low temperatures and the original softness is maintained.

3. Non-adhesive: not easy to adhere to any substance. It is easy to clean all kinds of oil stains, stains or other attachments attached to its surface; almost all adhesive substances such as paste, resin, paint, etc. can be easily removed.

4. Chemical corrosion resistance, can withstand the corrosion of strong acid, alkali and various organic solvents.

5. Low friction coefficient (0.05-0.1), is the best choice for oil-free self-lubrication.

6. The light transmittance is 6-13%.

7. With high insulation performance (different dielectric constant: 2.6, tangent below 0.0025), UV protection, anti-static.

8. Drug resistance, non-toxic. Almost all drug items are available.

9. Fire retardant.

Application range of General industrial grade PTFE coated fiberglass brown fabric:

1. Anti-adhesive lining, gasket, mask and conveyor belt; conveyor belt, adhesive tape and sealing tape used for various drying machines according to different thickness.

2. Welding of plastic products, welding cloth for welding and sealing; plastic sheet, film, heat sealing sheeting tape.

3. Electrical high insulation: electrical insulation tape base, spacers, gaskets, gaskets. High frequency copper clad laminate.

4. Heat-resistant cladding layer; laminated substrate, insulation body dressing.

5. Microwave gasket, oven sheet, food drying.

6. Adhesive tape, transfer printing ironing table cloth, carpet adhesive curing conveyor belt, rubber vulcanized conveyor belt, abrasive sheet curing release cloth and so on.

7. Pressure sensitive tape base fabric.

8. Building membranes: roofs of various sports venues, station pavilions, parasols, landscape tents, etc.

9. It is used for anti-corrosion coating of various petrochemical pipelines, environmental desulfurization of power plant exhaust gas, etc.

10. Flexible compensator, friction material and grinding wheel slice.

11. “Special anti-static cloth” can be made after special processing.

The main purpose of General industrial grade PTFE coated fiberglass brown fabric:

PTFE coated fiberglass fabric is widely used in aviation, paper, food, environmental protection, printing and dyeing, clothing, chemical, glass, medicine, electronics, insulation, construction (shelf film structure base fabric), because of its excellent performance. Grinding wheel slicing, machinery and other fields. Can be used for anti-corrosion coating, lining and liner, anti-adhesive conveyor belt, high frequency copper clad laminate, architectural membrane, insulation material, microwave drying conveyor belt, flexible compensator, friction material, etc.

According to different application requirements, different grades of PTFE coated fiberglass fabric can be produced, such as:

[General industrial grade]

PTFE coated fiberglass fabric has good heat resistance, anti-corrosion and non-stick properties, and is mainly used in various industrial fields.

[Standard grade]

Produced with imported materials, in addition to good anti-corrosion and heat resistance, the surface is smoother, flatter, and has good non-stick properties. It can be used in general industrial fields, as a release sheet for plastics or as a separator for some products, gaskets, and strips. The surface of the mold is more advantageous.

[Food grade]

The surface is smooth and flat, has good anti-adhesive properties, good heat resistance, easy to clean, and is safer to use in the food industry.

[Antistatic rating (antistatic cloth)]

In addition to the traditional properties of PTFE coated fiberglass fabric, it is treated with special processes to provide antistatic properties to meet customer specific requirements.
