PFA (Polytetrafluoro ethylene) is a copolymer of tetrafluoroethylene and perfluoroalkyl vinyl ether, and is a fluoropolymer that can be melt processed. It has various excellent properties such as high temperature and corrosion resistance equal to PTFE and good transparency. Compared with FEP, it has higher mechanical properties at high temperatures.

PFA sheet is mainly used for processing various parts and seals with excellent chemical stability, mechanical properties and electrical insulation in high temperature environments, and is used in a wide range of fields.

Feature
