Ceramic Fiber Board Introduction
Ceramic fiber board , also named as aluminum silicate fiberboard, a board made of refractory ceramic fiber material. Even after heating, ceramic fiber refractory board still has good mechanical strength. The product is a fibrous insulation product with rigidity and supporting strength than fiber blanket and felt.
Ceramic Fiber Board Properties
Low thermal conductivity
Low thermal capacity
Excellent thermal insulation property
High temperature stability
Resistance to thermal shock
Good tensile strength
Corrosion resistance.
Excellent sound absorption
Fire protection and chemical corrosion resistance
