The complete name of Teflon is Polytetrafluoroetylene, Referred to as the Teflon, PTFE, F4 etc. Polytetrafluoroethylene (Polytetrafluoroethene), commonly known as "non stick coating" is a use of fluorine substituted all hydrogen atoms in polyethylene synthetic polymer materials; Which has the advantages of acid alkali, resistance to various characteristics of organic solvents, insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, coefficient of friction is very low, so it can be used as lubrication of remaining, also became the ideal coating for pipe lining.
DuPont Co Teflon (Te Fulong) trademark is mainly used in the following products: PTFE, FEP, PFA, ETFE, AF, NXT, FFR.
PTFE:PTFE (polytetrafluoroethylene) nonstick coatings can be used continuously in 260 °C, with the highest use temperature of 290-300 °C, very low friction coefficient, good wear resistance and excellent chemical stability.
FEP:FEP (fluorinated ethylene propylene copolymer) non stick coating melt flow formed during baking no hole film, non stick properties has excellent chemical stability, excellent, high temperature up to 200 °C.
PFA:PFA (a fluoroalkyl compounds) non stick coatings and FEP in baking melt flow forming non porous films.
