Industrial PTFE Coated Fiberglass Fabric (Teflon Cloth)
1. Product Overview
Industrial PTFE coated fiberglass fabric (commonly known as Teflon cloth) is an engineered composite constructed from a dimensionally stable woven E-glass textile substrate impregnated and sintered with high-grade polytetrafluoroethylene (PTFE) fluoropolymer dispersion. The non-stick fluoropolymer encapsulation imparts low friction, moisture resistance, and universal chemical inertness across continuous operating temperatures. The internal fiberglass matrix prevents elongation, shrinkage, and mechanical deformation under high tension and heat. It is widely used across packaging, thermal lamination, and food manufacturing as a durable release barrier and conveying medium.
