Refractory bulk fibers are made from high quality Gao-ling clay, high purity alumina and silica oxides. The fibers are strong, high purity fibers unaffected by chemicals except for hydrofluoric and phosphoric acids and strong alkalies.
- Low thermal conductivity
- High heat resistance
- Resilient to thermal shock
- Corrosion resistance
- Manufacturing of blanket, paper, board, etc
- Loose insulating fill fro crowns and walls of kilns and furnaces
- Packing expansion joints in refractory constructions
