Lanmar #88-3 PTFE Coated Fiberglass Fabric (0.003”) is a tear & crease resistant, high-performance PTFE coated fiberglass material engineered for demanding industrial applications that require non-stick release, superior flexibility, and long service life. Constructed from woven fiberglass cloth and coated with PTFE (polytetrafluoroethylene), this fabric delivers a lightweight, low friction surface ideal for processes where creasing and handling stress can shorten material life. 

At 0.003” (3 mil) thickness, Lanmar #88-3 provides excellent mechanical flexibility with enhanced tear resistance, making it well-suited for applications involving repeated handling, folding, and dynamic surface movement. The PTFE coating produces a smooth, low-coefficient-of-friction finish that helps minimize product build-up, aid clean release, and maintain process consistency across heat sealing, transfer, and release operations. 

Designed to withstand continuous exposure in aggressive environments, this tear & crease resistant PTFE coated fiberglass fabric maintains performance across a broad temperature range from -400°F to +600°F, making it suitable for thermal, packaging, and contact surface protection where heat, abrasion, and contaminants are present. It also exhibits excellent chemical resistance and dimensional stability for long service life in high-performance industrial settings.
