1.5-6mm x 1500mm width Chinese PFA Anticorrosive Lining Sheet
PFA( Perfluoroalkoxy alkane) it kept a PTFE excellent chemistry stability, low, high temperature resistance, dielectric property, self-lubricating, anti-sticking, , ageing resistance, folding and cracking resistance are the outstanding characteristic of it, its mechanical strength in high temperature is more than 1.6 times as PTFE.
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,thepermittivitykeeps 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 alkaliscan 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
Easy to process for second time self-close, self-turning
Specification:
