Introduction:
FEPtube is made from FEP resin and prepared by the technology of thermoplastic extrusion and blowing. It has non-sticking, heat-resistance, aging resistance, corrosive resistance, non-flammability 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 200 and is an ideal material for circuit board and flat cable.
We can produce the tubes into rectangle shape, square shape, flared tube shape and Capped pipe shape.
Properties :
High low temperature resistance:
-200--200°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=1150o
Electric reliability,High dielectric
60HZ-60MHZ,Under the high and low temperature,thepermittivitykeeps2.1even if the surface damaged ,it won’t has conductive track.
Volume resistance>1018ΩM
Surface resistance>2*1013Ω
Voltaic Arc Resistance>165sNo electric leakageWeather 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
