Product Description
The PTFE sheet is divided into two types: mold molding and turning. The mold plate is formed by molding a polytetrafluoroethylene resin at a normal temperature, and then sintering and cooling. The PTFE turning plate is made of polytetrafluoroethylene resin by compacting, sintering and rotary cutting.

Product Features
Main features of PTFE sheet :
1. Temperature resistance ---It is able to work stably between -180°C to +260°C.
2. Excellent chemical corrosion resistance ---Applicable medium includes oil, acid solution and almost all chemical materials.
3. Excellent non-sticky property - --With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.
4. Anti-aging, weathering resistance.
5. Excellent insulation property.
6. Filled material: Filled PTFE products 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.
