GWDL- F The polycrystalline alumina fiber prepared by the sol-gel method is characterized by low volume weight, low thermal conductivity, good thermal shock resistance, high service temperature, good chemical stability and good corrosion resistance, etc. It is widely applied in metallurgy, building materials, ceramics, and aerospace industries.
1. Made into fiber insulating felt/board or special shaped fiber products used in furnaces with service temperature above1000-1600
2. Filling materials in expansion joints or short-term insulating patch
3. Reinforcing materials of the piston, brake block or other alloy composites
4. Heat insulating layer of the rocket motor or other insulating materials in the aerospace industry.
