MECHANICAL PTFE FABRIC

The Mechanical Series of PTFE Fabrics provides a more textured surface and is the most cost effective solution for applications where a mechanical impression must be transferred to a seal or where a surface texture is required. These fabrics are manufactured from woven fiberglass substrates and have a moderate PTFE content. They are food safe and FDA Compliant.

What is PTFE?

Polytetrafluoroethylene (PTFE), a fluorocarbon plastic, is a plastic in which the hydrogen normally found in association with carbon in organic materials has been replaced with fluorine. The resulting polymer possesses a number of unique properties: inertness to chemicals, fire resistance (will not support a frame); excellent weathering resistance; low friction (second only to ice); superior anti-stick properties; flexibility; extreme heat and cold resistance; outstanding electrical, insulative and dielectric properties; and resistance to ultraviolet (UV), infrared (IR), microwave and radio frequency (RF).

Mechanical PTFE Fabrics are manufactured in 4 common thicknesses: 0.003″, 0.005″, 0.009″, 0.010″, and 0.014″
