Ceramic Fiber Bulk

Ceramic Fiber BulkInsulfire refractory ceramic fiber bulk is made of high-purity raw material through blow process technique after high-temperature melting with some basic characteristics such as stable performance at high temperature, light weight, low heat capacity, good thermal shock resistance, corrosion resistance and sound absorption performance. Insulfire refractory ceramic fiber bulk is the basic material of insulfire ceramic fiber products.

Characteristics

Remain loose and good elasticity at high temperature
Low shrinkage at high temperature
Excellent thermal and chemical stability
Good thermal insulation and mechanical strength
Non-combustible, low thermal conductivity, low heat capacity
Easy to process and install
