Poly tetra fluoroethylene(abbreviated as Teflon or PTFE), commonly referred to as “non-stick coating” or “easy to clean materials.” This material is resistant to acids and alkalis and is resistant to various organic solvents and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used as a lubricant and it is also an ideal coating for easy cleaning of the inner layer of water pipes.
Polytetrafluoroethylene can be formed by compression or extrusion; it can also be made into an aqueous dispersion for coating, impregnation or fiber manufacture.
PTFE is widely used in atomic energy, defense, aerospace, electronics, electrical, chemical, mechanical, instrumentation, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgical smelting and other industries.
