Introduction:
FEP Tube 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. The shrink ratio is 30% . (1.3:1)

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=115o
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
Usages:
Widely used in aerospace,instrumentation,medical and pharaceuticals,electronic appliances,post and telecommunications,petrochemical,metallurgical electricity,household appliances,lighting.
