PFA round cake, PFA round 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.
Note: If you need any products of ours, please kindly contact with us
directly by following contaction . Then we can reply you faster and
easy . Thanks
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
