Polytetrafluoroethylene is commonly referred to as "" Non stick coating" Or "Easy to Clean Material": It is an artificially synthesized polymer material that uses fluorine to replace all hydrogen atoms in polyethylene glycol combustion. This material has the characteristics of acid resistance, alkali resistance, and resistance to various organic solvents, and is almost insoluble in all solvents. Meanwhile,PTFE film  has the characteristic of high temperature resistance and extremely low friction coefficient, making it an ideal coating for easy cleaning and the inner layer of water pipes.

The thin film is made of suspended polytetrafluoroethylene resin by molding, sintering, cooling into a blank, and then turning and rolling. The thin film obtained by turning is an undirected film, which is then compressed and stretched to form an oriented film. Non directional thin films are rolled 1.1 to 1.8 times as semi directional films. Polytetranitroethylene film is used as a dielectric for capacitors, as insulation for single edge traction of wires, and as a sealing material for instruments. PTFE film can be divided into PTFE colored film, PTFE activated film, and F46 film.

Polytetrafluoroethylene film performance characteristics

1. High temperature resistance, working temperature up to 250 ° C

2. Low temperature resistance: has good mechanical toughness: can maintain an elongation of 5% even when the temperature drops to -196C.

3. Corrosion resistance: It exhibits inertness and resistance to strong acids, alkalis, water, and various organic solvents for most chemicals and solvents.

4. Climate resistance: has the best aging life among plastics.

5. High lubrication: It is the lowest friction coefficient among solid materials.

6. Non adhesion: It is the minimum surface tension in solid materials and does not adhere to any substance

7. No toxicity: It is physiologically inert and has no adverse reaction after long-term implantation as an artificial blood vessel and organ.

8. Electrical insulation: capable of withstanding 1500 volts of high voltage.
