PFA - perfluoroalkoxylalkane
Perfluoroalkoxylalkane (abbreviation PFA)
Perfluoroalkoxy (PFA) is a type of polymeric fluorocarbons with properties similar to polytetrafluoroethylene (PTFE) and fluoroplastic fluoroethylene propylene (FEP). PFA is a fully fluorinated plastic and a copolymer PTFE and poly (perfluorovinylmethyl ether).
It is considered an evolution of PTFE. Both are under the brand name Teflon ™ expelled. PFA is resistant to almost all chemicals, has a high temperature resistance, a low coefficient of friction and is flame-retardant. PFA is also used as a hose and fitting material for aggressive chemicals. Non-stick coatings are also based on PFA, among others. Other bases of Non-stick coatings are among others PTFE - PTFE coating and FEP - FEP coating, PFA is also used in chemical plant construction Anticorrosion coating used.
