Fireproof PU Coated Fiberglass Cloth
Fireproof PU Coated Fiberglass Cloth: A Cost-Effective Solution for Thermal and Flame Insulation
Introduction
Fireproof PU (polyurethane) coated fiberglass cloth is a reliable industrial textile designed for thermal insulation, fire curtains, and smoke control systems. By combining a strong fiberglass base with a flame-retardant polyurethane coating embedded with aluminum pigment, this fabric offers both durability and excellent resistance to high temperatures.
What is Fireproof PU Coated Fiberglass Cloth?
This material is made by coating fiberglass fabric with a specially formulated polyurethane layer that includes aluminum pigment. The result is a lightweight, flexible, and flame-retardant fabric with excellent resistance to water, wear, and high heat.
