PFA is a copolymer of tetrafluoroethylene and perfluoroalkyl vinylether. It is a perfluoro polymer consisting of only carbon atoms and fluorine atoms without any hydrogen atom.
It has the same excellent performance as PTFE in a wide range from extremely low to high temperatures. In addition, it has excellent transparency, mechanical strength at high temperature. It can be molded in the same molding method as general thermoplastic resins.

Properties :

High low temperature resistance:
-200--260°C,high temperature strength is 2 times higher than PTFE
Good adhesive and heat sealability with PTFE:
Below melting point ,it won’t stick any project.Above melting point, it has perfect adhesive property with PTFE, Metal and
self-adhesion(heat sealing).
None stick to water ,oil : water contact angle: θ=115o
Electric reliability,High dielectric
60HZ-60MHZ , Under the high and low temperature,the permittivity keeps 2.1 even if the surface damaged ,it won’t has conductive track.
Volume resistance>1018ΩM
Surface resistance>2*1013Ω
Voltaic Arc Resistance >165s No electric leakage
Weather resistance: It can be used in sunlight and ozone long
Anti-corrosion :Only in high temperature, Fluorin and alkalis can effect it,others acid, alkali or ester won’t effect it.
Fireproof : If firing, and will still insulate .
High diaphaneity
UL-Resistance : Good penetrability in ultraviolet radiation,and lowest refraction coefficient
