Ceramic Fiber Blanket
Ceramic Fiber Blanket
Ceramic Fiber Blanket is made of special ceramic long fiber that is produced by melting very pure raw materials in double surface needing process. It also named aluminum silicate fiber blanket, because their main component is aluminum. It’s a new type of fire-resisting and heat-insulating materials with white color and accurate dimension. This product does not contain any adhesive to ensure their good stability in high temperature or low temperature environment.
Their Classification Temperature: 1050-1600°C.
Product Application
1.Lining, insulation and repair for furnaces, kilns, ovens, boilers;
2.Insulation for power plant, turbine, thermal reactor, generator, and nuclear applications;
3.Expansion joint seal and insulation;
4.Wrapping and insulation for high temperature pipe or metal casting;
5.Fire protective insulation and lining
6.Other high temperature seal, gasket, insulation or protection.
