What's PTFE?

Poly tetra fluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), commonly known as "plastic king", is a polymer made of tetrafluoroethylene as a monomer polymerization, chemical formula (C2F4)n, heat resistance, excellent cold resistance, can be used in -180 ~ 260ºC for a long time. Use. This material has the characteristics of resistance to acid and alkali, and resistance to various organic solvents, and is insoluble in almost all solvents. At the same time, PTFE has the characteristics of high temperature resistance, it has a very low coefficient of friction, so it can be used for lubrication, but also become the ideal coating for easy to clean the inner layer of water pipes.

PTFE uses.

1、Used in the electrical industry, in aerospace, aviation, electronics, instrumentation, computers and other industries as the insulation layer of power and signal lines, corrosion-resistant, wear-resistant materials can be made of film, pipe plate bar, bearings, gaskets, valves and chemical pipes, pipe fittings, equipment container lining, etc.

2、Used in electrical, chemical, aviation, machinery and other fields instead of quartz glassware used in atomic energy, medicine, semiconductor and other industries for ultra-pure chemical analysis and storage of various acids, alkalis, organic solvents can be made into highly insulating electrical parts, high-frequency wire and cable coverings, corrosion-resistant chemical vessels, alpine-resistant oil pipelines, artificial organs, etc. can be used as plastics, rubber, coatings, inks, lubricants, greases, etc. Additive.

3、Polytetrafluoroethylene high temperature resistance, corrosion resistance, excellent electrical insulation, aging resistance, small water absorption, excellent self-lubricating properties, is a general-purpose lubricity powder for a variety of media, can be quickly applied to form a dry film to be used as a substitute for graphite, molybdenum and other inorganic lubricants. Suitable as a release agent for thermoplastic and thermosetting polymers with excellent load-bearing capacity. Widely used in elastomer and rubber industries as well as in anti-corrosion.

4、Used as filler of epoxy resin to improve the abrasion resistance, heat resistance and corrosion resistance of epoxy adhesives.

5、Mainly used as the binder and filler of powder cake.
