High Silica Fiberglass Cloth (900–1200°C)

High Silica Fiberglass Cloth Manufacturer & Supplier for Extreme High Temperature Insulation

High Silica Fiberglass Cloth is a premium high-temperature insulation fabric manufactured from high silica fibers containing 96% or higher SiO₂ content. Designed for extreme heat protection, thermal insulation, welding safety, and fire protection, it provides outstanding resistance to continuous temperatures up to 1,000°C and short-term exposure up to 1,200°C.

Compared with standard fiberglass fabrics, high silica cloth offers significantly improved heat resistance, lower thermal conductivity, excellent thermal shock resistance, and superior molten metal splash protection. It is widely used in aerospace, foundries, metallurgy, shipbuilding, petrochemical plants, power generation, automotive manufacturing, and industrial furnace insulation.

As a professional high-temperature insulation material manufacturer, we supply high silica fiberglass cloth in rolls, cut sheets, die-cut components, coated fabrics, and OEM fabrication services for customers worldwide.

Product Benefits

High Silica Fiberglass Cloth provides reliable thermal protection in the most demanding industrial environments. Its high silica composition significantly reduces heat transfer while maintaining mechanical integrity under prolonged exposure to elevated temperatures.

The fabric is soft, flexible, and easy to sew, wrap, laminate, or fabricate into customized insulation products. It is commonly converted into welding blankets, fire curtains, removable insulation covers, expansion joints, and protective shields for high-temperature equipment.

Compared with ceramic fiber fabrics, high silica cloth produces less dust and offers better flexibility, making it easier to handle during installation and maintenance.
