1200Cel degree Polycrystalline alumina fiberboard

High temperature stability Low thermal conductivity Thermal shock Anti-erosion Easy processing and cutting performance

1 ProductsPolycrystalline alumina fiberboard is a wet vacuum filter press molding, use loose cotton and made of organic and inorganic binding agent. The product has a hard texture and excellent strength, anti-erosion, easy processing and cutting. Stable refractory fiber and chemical properties of its raw materials, and thus the light weight, good thermal insulation effect is a versatile product that can be applied to the lining hot face of anti-flame and high temperature airflow direct impact.2, FeaturesHigh temperature stabilityLow thermal conductivityThermal shockAnti-erosionEasy processing and cutting performancePrecise thickness and sizeGood resistance to flame and air scour3, product applicationA variety of high-temperature furnace lining or backingHigh-temperature fire block board and sealedFire insulation4, product data
