High Silica Fabric Welding Blanket Material - Fireproof & Thermal Resistant Textile
Product Description
The high silica fabric is a high-temperature fireproof textile designed primarily for welding blankets, fire curtains, thermal barriers, and heat insulation applications where extreme radiant heat and flame exposure are present.
Manufactured by BSTFLEX, this fabric is produced from high-purity silica sand (quartz-based fibers) and contains a very high silica content, providing excellent thermal stability, low shrinkage, and flame resistance.
Compared with standard fiberglass fabrics, silica fabric offers significantly higher temperature capability, making it suitable for heavy welding, cutting, furnace surroundings, and industrial fire protection.

Application Notice
High silica fabric should be selected based on actual heat exposure, radiant heat intensity, and molten metal risk to ensure optimal safety performance.
The high silica fabric manufactured by BSTFLEX is a professional fireproof and thermal-resistant textile specifically designed for welding blankets and high-temperature industrial protection.
With excellent flame resistance, low shrinkage, and multiple surface treatment options, silica fabric is an ideal material choice for environments where standard fiberglass fabrics are no longer sufficient.

Detals:
BST-SIF Silica Fiber cloth a high temperature fabric which is made by 70% +/-5% silica fibers and can almost cover most of industrial demands for temperature resistance, and with pefect tensile strength and abrasion resistant property.
Available with PSA adhesive backed.
It is used for equipment protection, welding curtains and blankets.
Available in standard sizes… or custom fabricated into almost any shape… or supplied in curtain format with factory-installed grommets to your specifications.
Dependable severe heat performance
Suitable for use at 1800°F (982°C), and able to withstand short term exposure up to 3000°F (1650°C), woven silica textile blanket is constructed from a 96% pure SiO2 silica fiber ─ a health-conscious alternative to asbestos and ceramic textiles.
Unmatched abrasion resistance and tensile strength
blankets set the standard for flexibility and minimum lineal shrinkage under high heat conditions. Durability is further enhanced with a proprietary hydrocarbon coating, giving silica blankets unmatched abrasion resistance and tensile strength.
Standard rolls or custom lengths. Two thicknesses.
Available in thicknesses of .030″ (.76 mm) and .050″ (1.27 mm). Standard 36″ (915 mm) width. Sold in 150 ft (45 m) rolls, or supplied in custom lengths.
