Expanded Fiberglass Fabric

Expanded Fiberglass Fabric – High-Performance Thermal & Fire-Resistant Material

Product Description

Expanded Fiberglass Fabric is a high-performance thermal insulation and fire-resistant fabric engineered for demanding industrial environments. Manufactured by RUISHUN using advanced expanding and texturizing processes on continuous fiberglass yarns, this fabric forms a thicker, bulky, and porous woven structure, significantly improving air retention and reducing thermal conductivity compared with conventional fiberglass fabrics.

The fabric retains all inherent fiberglass properties, including being non-combustible, flame-resistant, chemically stable, and electrically insulating. It performs reliably under continuous high-temperature conditions and provides effective thermal protection against radiant and convective heat. Its soft and flexible structure allows easy installation and wrapping around pipes, valves, flanges, and complex industrial equipment surfaces.

RUISHUN expanded fiberglass fabric exhibits excellent resistance to thermal shock, mechanical stress, and chemical corrosion, ensuring long service life in harsh industrial environments. It is fully compatible with silicone, vermiculite, aluminum foil, and PTFE coatings, which can further enhance abrasion resistance, moisture protection, flame resistance, and surface durability based on specific application requirements.

This material is widely applied in industrial insulation jackets, removable thermal covers, fire curtains, welding protection blankets, expansion joints, high-temperature gaskets, and sealing systems. Typical application industries include power generation, petrochemical processing, metallurgy, shipbuilding, HVAC systems, and industrial equipment manufacturing.

With consistent quality, stable structure, and flexible customization capabilities, RUISHUN expanded fiberglass fabric provides a cost-effective and reliable solution for industrial heat insulation and fire protection. Specifications such as fabric thickness, weight, width, weave density, and surface treatment can be customized to meet different engineering standards and project requirements.
