PTFE Film

PTFE (polytetrafluoroethylene) film is made of PTFE resin by molding, sintering, cooling into blank, then by turning, calendering.

The PTFE thin film made by turning is a non-oriented film, which becomes a oriented film after calendering.

The non-oriented film is semi-oriented film by calendering 1.1-1.8 times.

PTFE's excellent electrical insulation, high and low temperature resistance and not sticky, especially the dielectric properties of its impact is not affected by environment and frequency, develop its wide application in electronic and electrical appliances. As one of the leading PTFE film manufacturers, Our embryo is made of PTFE resin with quality high cleanliness. After the production process of truning and pressing the directional. It can be made into semi directional and oriented PTFE film, clean, smooth and excellent dielectric properties characteristics.

PTFE Film Roll Features

Temperature resistance: It is able to work stably between -180°C to +260°C.

Excellent chemical corrosion resistance: Applicable medium includes oil, acid solution and almost all chemical materials.

Excellent non-sticky property: With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.

Anti-aging, weathering resistance.

Excellent insulation property.

Filled material: Filled PTFE has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.

PTFE Film Uses

Electrical instrument gaskets used in various media.

Capacitor media.

Wire wrap insulation.

Can also be used as anticorrosive, high temperature resistant sealing or anti-friction materials.

Color film is a small section of high temperature resistance and easy to distinguish wire ideal insulation material.
