0.4mm Grey Single Sided PTFE Coated Fiberglass Fabric
1. Product Overview
0.4mm grey single-sided PTFE coated fiberglass fabric is an engineered composite designed primarily as an external protective facing for high-performance removable insulation systems. The woven E-glass substrate is coated on one side with high-grade polytetrafluoroethylene (PTFE) resin, imparting hydrophobic, oleophobic, and UV-resistant characteristics to shield internal insulation mats against moisture ingress and chemical splashes. The untreated reverse side retains the raw mechanical texture of the fiberglass fabric, facilitating optimal grip, sewing stability, and adhesive bonding with ceramic fiber or needle-punched glass mat cores.
