pure skived PTFE film products
Ptfe orientation film is make of PTFE resin through green compact,sinter and skiving ,then through calendar,so the molecular arrangement of PTFE oriented membrane is tighter than other PTFE films,and has more obvious anti-voltage intensity
Application
Lining,sealing and lubricating material and dielectric at any frequency.Wire insulation,electrical instrument insulation,especially in the fields of making capacitors
