Alumina Silicate Refractory Fiber Blanket

Alumina-silicate Refractory Fiber Blanket

Aluminum silicate fiber blanket is a kind of inorganic fiber heat insulation material with excellent properties. It is mainly made of natural ores such as coke gems and kaolin by high temperature melting and blowing. The main chemical composition is alumina (Al₂O₃) and silicon dioxide (SiO₂), the alumina content is generally about 45%-55%, and the rest is silicon dioxide and other components.

Features of Alumina-silicate Refractory Fiber Blanket:

low thermal conductivity
good high temperature resistance
good chemical stability
sound absorption and noise reduction
good flexibility.
