Teflon plate also has excellent resistance to high and low temperature function and chemical not disorderly, good electric has been in the chemical industry, petroleum, textile, this series of products with excellent high temperature resistance, wear resistance, corrosion resistance, ageing resistance, flame retardant, excellent dielectric properties (strength) insulation oven oven and self-lubricating characteristics, widely used in spray gun, diaphragm pump, metering pump and other kinds of pumps, filling all kinds of different material or coating material, different parts. Tetrafluoroethylene is also known as teflon, ptfe, plastic wang, tetrafluoroethylene, ptfe, F4, teflon and so on. Sub-electrical, medical, mechanical and other fields have been widely used. Among fluoroplastic polytetrafluoroethylene (ptfe) consumption is the largest, "plastic king" beauty. Ptfe material was first developed for national defense and cutting-edge technology needs, ptfe products have excellent high temperature resistance wear resistance and self-lubrication and other characteristics of graphite, an important variety. Its USES are related to aerospace and civil many aspects, ptfe board with its excellent resistance to high and low temperature function and chemical stability, good electrical insulation function, insulation function, non-adhesion, weather resistance, flame retardant and good self-lubrication, household appliances, polystyrene, etc.. The filling materials are glass fiber, such as: magnet coating, rubber, bearing, steel plate... Gas (liquid) pressure machinery, pneumatic tools, carbon fiber, medical apparatus and instruments is fluorine plastic in adhesion, weather resistance, flame retardancy and good self-lubrication, the most widely use, and then gradually spread to the civilian, according to the product at the same time use the pressure, temperature, insulation, chemical corrosion resistance and wear resistance, the current in the field of its application has become the indispensable materials.


Ptfe board can be compressed or extruded into shape. It can also be made into water dispersions for coating, dipping, or making fibers. Ptfe in atomic energy, defence, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgical smelting and other industries widely used for high and low temperature resistance, corrosion resistant materials, insulation materials, anti-sticking coating, etc., make it become the irreplaceable products. Ptfe has outstanding comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubrication, excellent dielectric properties, very low friction coefficient.

1. Used as engineering plastics, can be made into ptfe tube, rod, tape, plate, film, etc.

2. Generally used in corrosion resistant pipelines, containers, pumps, valves and radar, high-frequency communication equipment, radio equipment, etc. The mechanical properties of ptfe can be greatly improved by adding any filler which can withstand the sintering temperature of ptfe. At the same time, it maintains other excellent properties of ptfe.

3. The filled varieties are glass fiber, metal, metallized oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL... The wear-resistant and limiting PV value can be increased by 1000 times. Teflon cloth teflon tube is made of suspended polytetrafluoroethylene resin by plunger extrusion. Ptfe has the best chemical corrosion resistance and dielectric properties among known plastics.

4. Ptfe braided packing is a good dynamic sealing material. It is made of expanded polytetrachloroethylene tape. Ptfe braided packing is a good dynamic sealing material. It is made of expanded polytetrachloroethylene tape. It has low friction coefficient, wear resistance, chemical corrosion resistance, good sealing, no hydrolysis, no hard and other excellent performance.

5. Gasket seals and lubricating materials used in various media, as well as electrical insulation parts used at various frequencies. Capacitor dielectric, wire insulation, electrical instrument insulation, etc. Ptfe film is suitable for capacitor dielectric, special cable insulation layer, conductor insulation, electrical instrument insulation and sealing gasket, but also for non-stick tape, sealing tape, demoulding.

6. Ptfe classification and its filling products all kinds of common materials rods, tubes, plate membrane, belt, rope, packing, gasket, and use graphite, molybdenum disulfide, aluminum oxide, glass fiber, carbon fiber as filler, to improve the mechanical properties of pure ptfe.

Ptfe board anti - corrosion performance anti - corrosion class
