PFA RESIN

PHYSICAL & CHEMICAL PROPERTIES:

PFA is one kind of hypocrystalline and translucent polymer, the specific gravity is 2.14~2.18. PFA has excellent chemical stability, mechanical property, electrical insulation, lubricating property, non-viscosity and non-combustibility, aging resistance. The melting point of PFA is 300~320℃, upper service temperature range is 260℃, pyrolysis is more than 450℃. PFA provides excellent thermoplasticity.
