PTFE coating is divided into several basic types of PTFE, FEP, PFA, ETFE:
PTFE:PTFE (polytetrafluoroethylene) non-stick coating can be used in 260 ℃, maximum operating temperature is 290-300 ℃, low friction coefficient, good abrasion resistance and excellent chemical stability.
FEP:FEP (fluorinated ethylene propylene copolymer) non-stick coating melt flow form non-porous membrane when baking, has excellent chemical stability, excellent non-stick properties. 
PFA:PFA (fluorine alkylate) non-stick coating and FEP melt flow form non-porous membrane during baking.PFA has the advantage of continuous temperature 260 ℃, has higher stronger toughness, especially suitable for use under the condition of high temperature resistant glue and chemical resistance field.
ETFE:ETFE is an ethylene copolymer about ethylene and tetrafluoroethylene, the resin is the most tough fluorine polymer, can form a layer of highly durable coating has excellent chemical resistance, and can work continuously under 150 ℃.
