PTFE Skived film


1. Product Features

PTFE skived film is made from PTFE resin and prepared by compression molding, skiving and calendaring technology. This film has excellent chemical resistant, ageing resistant and dielectric property, used as capacity medium, electric device, wire and cable insulation. There are three kinds of film :Ⅰoriented film, used as capacitor medium. Ⅱ semi-oriented film, used as wire insulation. Ⅲ non-oriented film, used as insulation,sealing material in electric devices and instruments and anti-stick material at high temperature. It conforms to the professional standard QB/T 4876-2015.

2. Application

Typical applications include electronic technology, food technology, chemical technology, communications, aerospace, military and other fields, because of its good electrical properties, heat resistance, chemical resistance and fire resistance to climate, making it particularly suitable for electrical instrumentation radio insulation materials, wire and cable insulation protection layer, the cable liner material; at the same time it can also be used as demoulding and debonding materials.
