It has a silica content of 96–98%, a continuous temperature resistance of 1000 degrees Celsius, and a short-term temperature resistance of 1400 degrees Celsius; its finished products mainly include continuous yarn, rope, casing, mesh, and stitch-stitched products. They are mainly used for 1000 degree ultra-high temperature fire insulation. Single fiber diameter is more than 5 microns, does not contain any asbestos or ceramic wool, and is completely harmless to health.
Silica fiberglass fiber maintains good strength and elasticity for a long time at 1000 °C. It is an effective thermal barrier for ultra-high temperature heat flow and jet flame, and a reliable protection device for personnel facilities. It has low thermal conductivity, good resistance to high thermal shock, and is inert to most chemicals. It has good corrosion resistance to compounds, corrosive minerals and weakly alkaline molten alloys at high temperatures, and works normally under high heat and strong radiation conditions.
At present, it has been widely used in spacecraft heat-resistant ablation materials, high-temperature insulation, high-temperature gas dust collection, liquid filtration, metal melting filtration, purification, etc. It has a very broad application prospect and huge market potential.
