Among plastics, fluororesins possess rare characteristics. An explanation of the representative fluororesins "PTFE," "PFA," and "FEP."
What are the representative fluoropolymers with the highest characteristics of plastic? Here, we will explain three representative fluoropolymers.
■Resin Name
PTFE (Polytetrafluoroethylene)
■Features
It has the highest continuous use temperature of 260°C, and is excellent in heat resistance, non-stick properties, and low friction characteristics.
■Also Known As
Tetrafluoroethylene, 4F
■Resin Name
FEP (Perfluoroethylene Propylene Copolymer)
■Features
This is a modified resin of PTFE, with a continuous use temperature of 200°C. It has a low thermal melt viscosity, allowing for molding through injection molding, which was not possible with PTFE. Its heat resistance temperature is lower than that of PTFE.
■Also Known As
4F6F, Tetrafluoro-hexafluoropropylene
■Resin Name
PFA (Perfluoroalkoxy Alkane Polymer)
■Features
This is a modified resin of PTFE that has the same heat resistance of 260°C as PTFE. It has a low melt viscosity, making injection molding possible, which was not feasible with PTFE.
