Product Description

High silica chopped yarn is a high-temperature resistant inorganic fiber made from glass fibers with a SiO₂ content of 96 % or higher. It combines excellent thermal stability with strong chemical and electrical insulation performance, making it ideal for demanding industrial environments.

Main Characteristics:

• SiO₂ content ≥ 96 %

• Softening point close to 1700 °C, continuous use at up to 1000 °C

• Low thermal conductivity for efficient heat insulation

• Outstanding chemical and corrosion resistance

• Excellent electrical insulation properties

• Non-asbestos, environmentally friendly, and pollution-free

• Good processability — easy to mix, mold, and form into composites

Performance Features:

High silica chopped yarn offers exceptional thermal shock resistance, slag resistance, acid and alkali resistance, hydration and oxidation stability, as well as resistance to CO erosion and electrical conductivity degradation. Its reliable performance ensures long-term durability under high-temperature and chemically aggressive conditions.

Applications:

This material is widely used across the metallurgy, chemical, petroleum, machinery manufacturing, silicate, and power industries. It is primarily applied in the production of:

• High-silica glass fiber needled felts

• Nano-porous thermal insulation boards

• High-temperature-resistant engineering plastics and injection-molded components

With a refractoriness of not less than 1580 °C, high silica chopped yarn can resist softening or melting under load-free high-temperature exposure. Such refractory materials are essential in industrial sectors—especially metallurgy, which accounts for more than 50 % of total global usage.
