PFA: excellent chemistry stability, low,high temperature resistance,dielectric property,self-lubricating ,anti-sticking.
PFA
PFA (also named fusible polytetrafluoroethylene), it kept PTFE excellent chemistry stability, low, high temperature resistance, dielectric property, self-lubricating, folding and cracking resistance are the outstanding characteristic of it, its mechanical strength in high temperature is more than 1.6 times as PTFE.
