What is the main content of Teflon coating? Teflon coating, also known as iron fluoride, is a specialized high-performance coating (paint) that combines heat resistance, chemical inertness, excellent electrical insulation stability, and low friction properties. It boasts comprehensive advantages unmatched by other coatings. Its versatile applicability makes it widely used in kitchenware, tableware, furniture, molds, home appliances, automobiles, machinery, and technology, among others.

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

Teflon PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at high temperatures up to 260°C, with a maximum operating temperature of 290-300°C. It boasts a low coefficient of friction, excellent wear resistance, and good chemical stability.

Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating melts and flows during baking to form a poreless film, boasting excellent chemical stability, good non-stick properties, and a high operating temperature of 200°C.

Teflon PFA: PFA (perfluoroalkylated) non-stick coatings, like FEP, melt and flow upon baking to form a poreless film. The advantages of PFA include a higher continuous use temperature of 260°C and greater toughness, making it suitable for applications requiring non-stick and chemical resistance under high-temperature conditions.

Teflon ETFE: ETFE is a copolymer of ethylene and tetrafluoroethylene, a robust fluoropolymer resin capable of forming a highly durable coating with excellent chemical resistance and can operate continuously at temperatures up to 150°C.
