PFA lining sheet, PFA anticorrosive sheet/board , PFA semiconductor 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 PTFEGood 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=1150oElectric reliability,High dielectric60HZ-60MHZ ,Under the high and low temperature,thepermittivitykeeps 2.1 even if the surface damaged ,it won’t has conductive track.

Volume resistance>1018ΩMSurface resistance>2*1013ΩVoltaic Arc Resistance>165s No electric leakageWeather resistance:It can be used in sunlight and ozone longAnti-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
