PFA round mould-pressing cake, PFA round mould-pressing 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=1150o
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
