Product Description
Ptfe Teflon Film has the merit of most remarkable anti-voltage intensity, and high breakdown voltage. It is used for capacitor medium,wire insulation, electric appliance, meters insulation, sealing interleaver. Ptfe Teflon Film is made of PTFE resin through green compact,sinter and turning. A kind of directional membrane made of Ptfe Teflon Film through calendar, the crystallilinity is high, molecule direction detection tight arranges, minimum voids percentage, so Ptfe Teflon Film improves a lot ,especially more obvious anti-voltage intensity
