DuPont company Teflon (Teflon) trademarks are mainly used in the following products: PTFE, FEP, PFA, ETFE, AF, NXT, FFR.
PTFE:PTFE (PTFE) Non-stick coating can be used continuously in 260 ℃, with a maximum temperature of 290-300 ℃, very low friction coefficient, good wear resistance and excellent chemical stability.
FEP:FEP (ethylene fluoride propylene copolymer) Non-stick coating in the baking melt flow formation of a hole-free film, with excellent chemical stability, excellent non-stick characteristics, the maximum use temperature of 200 ℃. PFA:PFA (over fluorine alkyl) Non-stick coating, like FEP, melts and flows into a hole-free film during baking. The advantage of PFA is that it has a higher continuous operating temperature of 260 ℃, stronger rigid toughness, and is particularly suitable for use in the field of adhesion and chemical resistance in high temperature conditions.
