We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Ceramic wool insulation includes: standard type, high purity type, high alumina type, containing zirconium type.
Product introduction of ceramic wool insulation
Ceramic wool insulation for furnace lining is processed with high purity clay clinker, alumina powder, silica powder, chromite sand and other raw materials. Ceramic fiber cotton can be further processed into fiber blanket, board, paper, cloth, rope and other products.
Features of ceramic wool insulation
- Light weight
- High strength
- Antioxidation
- Low thermal conductivity
- Corrosion resistance
- Low heat capacity and sound insulation
