Polycrystalline Alumina Fiber Module-cut is from polycrystalline alumina fiber by special process finishing cutting, compression formed. Does not contain any binders or other ingredients, with excellent elasticity and flexibility, the maximum temperature up to 1600 ℃. They oxidizing atmosphere, the neutral atmosphere, the long-term bear this temperature, still maintain their original toughness, strength, flexibility and fiber structure, and non-residue ball, can be used by a variety of high-temperature industrial furnaces hot face lining paste, has a special significant insulation performance.
Used as module-cut of working lining for various furnaces such as the heating furnace, soaking furnace, heat treatment furnace, and ceramic fast firing kiln, and sealing materials for furnace door or cover.
