The Industrial Woven Fiberglass Coated Series is our most versatile and commonly used PTFE Fabric. They are food safe and FDA Compliant. They offer an excellent balance between heat transfer, release and flexibility. These fabrics are manufactured from woven fiberglass substrates, possess an optimal PTFE content, and leave a minimal fabric impression. This series of industrial fabrics is engineered to serve a broad range of industrial and general purpose applications.

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″
