PFA pipe fitting , PFA elbow ,PFA joint, PFA processed parts
PFA has non-sticking, heat-resistance, aging resistance, corrosive resistance, non-lammability and good electric property.
It can be solid adhesive for PTFE and also a good adhesive for laminating various materials. Its working temperature is up
to 260 and is an ideal material for circuit board and flat cable.
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
