What is the main content of Teflon spray?

       What is the main content of Teflon spray? Chinet pointed out: Teflon (Teflon) coating is a special high-performance coating (paint), which combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has no other coatings. Competing with the comprehensive advantages, its flexible applicability makes it widely used in: cooking utensils, tableware, furniture, molds, home appliances, automobiles, machinery, medicine, technology and so on.



Teflon is divided into four types: PTFE, FEP, PFA, and ETFE.

Teflon PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at a high temperature of 260 ° C, the highest use temperature can reach 290-300 ° C, extremely low friction coefficient, good wear resistance and excellent chemical stability.

Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a non-porous film, with excellent chemical stability, excellent non-stick properties, and a maximum service temperature of 200°C.

Teflon PFA: PFA (perfluoroalkylate) nonstick coatings, like FEP, melt flow to form a non-porous film when baked. The advantages of PFA are that it has a higher continuous use temperature of 260 ° C, stronger rigidity and toughness, and is suitable for anti-sticking and chemical resistance applications under high temperature conditions.

Teflon ETFE: A copolymer of ethylene and tetrafluoroethylene, ETFE is the toughest fluoropolymer resin and can form a highly durable coating with excellent chemical resistance and can withstand temperatures up to 150°C continuously working.
