PFA membrane for PTFE Copper clad , PFA film for Iron floor
PFA film is made from PFA 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 260 and is an ideal
material for circuit board and flat cable.
Applicaton :
Bonding Material
To bond PTFE fiber glass tape,PTFE conveyor,Tent lap
PTFE sheet welding film
Iron baseboard fabrication
Mid adhesive layer of PTFE Copper clad
Dielectric
Te be the basic material of high temperature adhesive tape
Capacitor insulation
Lining Material of anticorrosive
Release film
Window film
Biology Copious cooling Protective material
Non-metallic compensator used in thermal power plant
Anti-explosion electric motor
Surface protected material
Semiconductor assembly material
Properties :
High low temperature resistance:
-200--260°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,the permittivity keeps 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 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
