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.

Features

  • Low thermal conductivity
  • High heat resistance
  • Resilient to thermal shock
  • Corrosion resistance

Application

  • Manufacturing of blanket, paper, board, etc
  • Loose insulating fill fro crowns and walls of kilns and furnaces
  • Packing expansion joints in refractory constructions
