Woven Silica Fabric – Engineered for Extreme Heat and Industrial Durability

July 27 , 2025

Woven silica fabric is a high-performance thermal protection material designed to withstand some of the most demanding industrial environments. Made from amorphous silica fibers with a purity of over 96%, this fabric provides exceptional resistance to high temperatures, thermal shock, and chemical attack. It is widely recognized for its ability to maintain structural integrity at continuous operating temperatures up to 1000°C (1832°F), making it an ideal choice for heavy-duty insulation and heat shielding applications.

Woven Silica Fabric

Product Features and Performance

Extreme Heat Resistance: Capable of withstanding short-term exposure up to 1650°C (3000°F), woven silica fabric offers reliable protection against open flames, molten metal splashes, and radiant heat.
Low Thermal Conductivity: Its superior insulation properties minimize heat transfer, helping to maintain consistent temperatures and protect sensitive components.
Chemical and Abrasion Resistance: Resistant to most acids, alkalis, and solvents, while maintaining strength and flexibility under mechanical stress.
Low Smoke and Low Outgassing: Suitable for aerospace and high-tech applications where contamination must be minimized.

Applications Across Industries

Welding and Metalworking: Used as welding blankets, heat shields, and protective curtains to guard workers and equipment from sparks, spatter, and molten metal.
Aerospace and Automotive: Applied as thermal barriers in engine compartments, exhaust systems, and fireproofing solutions.
Marine and Shipbuilding: Provides fire protection and heat insulation for engine rooms, bulkheads, and exhaust pipelines.
Foundries and Glass Manufacturing: Serves as a protective cover or insulation layer in furnaces and ladles, preventing heat loss and equipment damage.
Power Generation: Employed in turbines, boilers, and high-temperature pipe insulation for improved energy efficiency and safety.

Production Process

The manufacturing of woven silica fabric involves advanced weaving technology, starting with high-purity silica yarns. These yarns are derived from leached glass fibers that undergo chemical treatments to achieve superior thermal and chemical stability. The fibers are then woven into fabrics with various thicknesses, weights, and weave patterns—such as satin or plain weave—depending on the intended application. Additional treatments, such as vermiculite or silicone coatings, can be applied to enhance abrasion resistance or reduce fraying.

Advantages Over Traditional Materials

Outperforms standard fiberglass fabrics in high-temperature applications.
Non-combustible and retains flexibility even after prolonged heat exposure.
Can be cut and sewn easily to fabricate custom thermal covers, blankets, and pads.
Eco-friendly and free of asbestos, providing a safe alternative for industrial insulation.

Why Choose Woven Silica Fabric?

Industries that demand consistent performance under extreme conditions rely on woven silica fabric due to its combination of durability, heat resistance, and chemical stability. Its versatility allows it to be used both as a standalone thermal barrier and as part of multilayer insulation systems. Whether protecting sensitive components from heat damage or enhancing energy efficiency, woven silica fabric is a trusted solution.
