Medium silica fiberglass fabric (SiO₂ content: 70%±5%) is a high-temperature resistant inorganic fiber material designed as a cost-effective alternative to high-silica fiberglass in moderate-temperature applications. It is asbestos-free and non-hazardous, offering balanced thermal and mechanical performance for industrial use.
