• DESCRIPTION

High silica chopped yarn is made by cutting high silica fiberglass yarn into short lengths, forming an inorganic fiber for high-temperature applications.

With SiO₂ ≥96% and a filament diameter of 6–9 μm, it offers stable chemical properties without brittleness, dissolution, or volatilization. Its softening point is 1700°C, enabling continuous use up to 1000°C.

It is an effective alternative to asbestos and ceramic fibers, providing safer, more durable, and environmentally friendly thermal insulation.

• PROPERTIES

Ø Low thermal conductivity for excellent insulation performance.

Ø Outstanding chemical stability with strong corrosion resistance; inert to most chemicals.

Ø Good electrical insulation properties.

Ø Asbestos-free and ceramic fiber-free, safe for human health.

Ø Excellent dispersibility, ideal for high-temperature boards such as nano insulation panels.

• APPLICATION

Ø Used directly as thermal insulation filling.

Ø Raw material for silica needle mats, silica paper, and nano insulation panels.

Ø Suitable for spray molding of high-temperature plastics.

Ø Can reinforce phenolic resin to produce ablation-resistant materials.
