In addition to having the corresponding bulk ceramic fiber ceramic fiber cotton excellent performance, the product hard, good toughness and strength, has excellent resistance to wind erosion. Heating does not swell, lightweight, easy construction, can be cut bending furnace is an ideal energy-saving materials, pipes and other thermal devices. High strength, long life; low heat capacity, low thermal conductivity; good non-brittle material, toughness; precise size, good flatness; easy to install and easy to cut and construction; excellent resistance to weathering performance; continuous production, uniform fiber distribution stable performance. Applications furnace cement and other building materials industry backing insulation; petrochemical, metallurgy, ceramics, glass industry furnace insulation backing; heat treatment furnace insulation backing; non-ferrous metal industry backing insulation; high temperature reaction, heating equipment backing Insulation
