PU Coated High Silica Fabric | Heat Resistant Fiberglass Cloth for Welding Blanket & Fire Curtain
Polyurethane Coated Fabric Introduction
This (Silica + Heavy-Duty PU) fiberglass fabric is a high-performance composite material designed for demanding welding and high-heat environments. With a weight of 460 g/m² and a thickness of 0.41 mm, it combines silica fiber strength with a durable polyurethane coating to enhance flexibility, abrasion resistance, and surface protection.
It offers excellent resistance to sparks, molten metal splashes, and high temperatures, making it ideal for welding blankets, fire curtains, and industrial thermal shielding applications. The material ensures reliable protection while maintaining good handling performance for cutting, sewing, and fabrication.

Advantages of Fiberglass Cloth
Fiberglass fabric remains the most commonly used reinforcement material in the composites industry. Fiberglass is the lowest-cost and easiest to process of all reinforcement materials. Furthermore, when combined with resin, fiberglass fabric offers strength, light weight, and excellent appearance.
When selecting industrial fiberglass fabric, many specific parameters need to be considered. These parameters can be categorized into four basic variables: yarn weight, warp count, weave pattern, and fabric surface treatment.
The wide variation in fiberglass yarn weight and warp count provides the basis for fabric design. Together, yarn weight and warp count determine the fabric's strength, weight, and thickness.
Fiberglass fabric is manufactured using basic weave types. There are five basic weave patterns for industrial fiberglass fabric: plain, twill, satin, leno, and basket weave.
The fabric structure is determined by the number of warp and weft yarns per inch of fabric and the weave pattern.
The surface treatment of fiberglass fabric is important. Most applications require the use of a coating material with the fiberglass fabric. For compatibility with resin coating, organic coating or post-treatment, perform surface treatment.
