What is the High Silica Cloth?

High Silica Cloth is a kind of heat-resistant, soft, special crystal fiber fabric with SiO2 content of more than 96%. The product has excellent heat resistance and can be used under 1000°C for a long time. The instantaneous heat resistance temperature can reach 1400°C. The glass raw material of Na2O-B2O3-SiO2 ternary system is adopted, and the softening point temperature of the acid processor is 1700°C.
