Product introduction of ceramic fiber blanket
Ceramic fiber blanket is made of special aluminum silicate ceramic fiber filament by special double-sided needle punching process. The interlacing degree, delamination resistance, tensile strength and surface smoothness of the fibers have been greatly improved after double-sided acupuncture treatment. The fiber blanket does not contain organic binder to ensure the good workability and stability of ceramic fiber blanket under high and low temperature conditions.
Features of ceramic fiber blanket
White, uniform in size, integrating fire resistance, heat insulation and thermal insulation. Does not contain any binding proxies. Long term use in neutral and oxidizing environments can maintain good tensile strength, toughness and fiber structure. The temperature resistance is 950-1400 ° F.
