What is Teflon? What is the difference between PTFE, PFA, FEP, and ETFE?

Teflon products, also known as polytetrafluoroethylene products

As is well known, Teflon products can be referred to as "PTFE products", "PTFE products", "PTFE products", "PTFE products", "Teflon products", "Plastic King", and so on. Many friends do not know that PTFE is Teflon, and they cannot distinguish Teflon from PTFE, PFA, FEP, ETFE very well. So today, let's take a look at what Teflon is? What is the difference between PTFE, PFA, FEP, and ETFE?

Polytetrafluoroethylene, also known as Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, is a transliteration name of a kind of coating. Its English name is PTFE. It is mainly a kind of fluoro coating with PTFE as the matrix resin. Polytetrafluoroethylene coating is a kind of high-performance coating, which has excellent chemical inertia, heat resistance, non adhesion, wear resistance, high insulation stability and extremely low friction, It has many comprehensive advantages that coatings cannot compete with.

The difference between Teflon and PTFE, PFA, FEP, ETFE:

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

PTFE, also known as polytetrafluoroethylene, its non stick coating can be used continuously at the temperature of - 190~+260 ℃, and its use temperature can reach 290-300 ℃. It has extremely low friction coefficient, good wear resistance and excellent chemical stability;

FEP, also known as fluorinated ethylene propylene copolymer, is used at 200 ℃. It has chemical stability and excellent non adhesion. Its non stick coating can melt and flow during baking to form a five hole film.

PFA, also known as perfluoroalkyl compounds, has a non stick coating that, like FEP, melts and flows during the baking process, forming a porous film. PFA has stronger stiffness and toughness, making it suitable for anti stick and chemical resistance applications under high temperature conditions. Its operating temperature is 260 ℃.

ETFE is a copolymer of ethylene and tetrafluoroethylene that can work continuously at 150 ℃. It is a tough fluoropolymer resin with excellent chemical resistance and can form a highly durable coating.
