What is teflon fabric?

Teflon high functional special coating is ptfe as the base resin of fluorine coating, English name for Teflon, because of pronunciation, usually also known as Teflon, Teflon, Teflon, Teflon and so on (all for the translation of Teflon).

Teflon is divided into PTFE, FEP, PFA, ETFE several basic types: TEflon PTFE: PTFE (polytetrafluoron) non-stick coating can be continuously used at 260 deG C, with a maximum use temperature of 290-300 DEG C, very low friction coefficient, good wear resistance and excellent chemical stability. Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts during baking to form a non-porous film, with excellent chemical stability, excellent non-stick properties, the highest operating temperature is 200℃. Teflon PFA: PFA (perfluoroalkyl) non-stick coatings, like FEP, melt during baking to form a porous film. The advantages of PFA are higher continuous use temperature of 260℃, stronger toughness, especially suitable for the use of high temperature under the premise of anti-stick and chemical resistance in the field of use. Teflon ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene. The resin is the toughest fluoropolymer, forming a highly durable coating with excellent chemical resistance continuous operation at 150 °  C.

After being coated with Teflon, it has the following characteristics:

1, non-viscosity: almost all substances are not bonded with teflon film. Very thin membranes also show excellent non-adhesion properties.

2, heat resistance: Teflon film has excellent heat resistance and low temperature resistance. Short time can withstand high temperature to 300℃, generally between 240℃~260℃ can be used continuously, with obvious heat is not disorderly, it can work at freezing temperature without embrittlement, does not melt at high temperature.

3, sliding: Teflon film has a low coefficient of friction. When the load slides, the friction coefficient changes, but the value is only between 0.05 and 0.15.

4, moisture resistance: teflon film surface does not stick to water and oil, production control is not easy to stick to the solution, such as a small amount of dirt, simple wipe can be removed. Short downtime, save time and improve work efficiency.

5, wear resistance: under high load, with excellent wear resistance function. Under a certain load, it has the dual advantages of wear resistance and non-adhesion.

6. Corrosion resistance: Teflon is almost resistant to drug corrosion and can protect parts from any kind of chemical erosion.
