Definition
heat insulating ceramic fiber blanket for annealing high temp ceramic fiber mat is made of special ceramic long-fiber that is produced by melting high pure raw materials in double surface needle punching technology. It also named aluminum silicate fiber blanket, it's a new type of fire-resisting and heat-insulating materials with white color and accurate dimension.
Feature
heat insulating ceramic fiber blanket for annealing high temp ceramic fiber mat have Excellent chemical stability & heat stability, High tear strength, Low heat conductivity and Low thermal capacity.
