PU Coated Fiberglass Fabric
1. Product Overview
PU coated fiberglass fabric is a high-performance industrial textile constructed from a precision woven E-glass substrate impregnated and coated with a specially formulated polyurethane (PU) elastomer. The polyurethane coating seals the glass filament pores, preventing fraying, skin irritation, and moisture penetration while imparting high flexibility, abrasion resistance, and gas-tight sealing properties. The material withstands continuous operating temperatures up to 550°C for the fiberglass core, providing reliable thermal protection and mechanical durability in harsh industrial environments.
