Product Introduction
Products Description

 

High alumina insulation brick is a new type of thermal insulation brick in the lightweight high alumina brick series. It is mainly made of high alumina clinker and high purity clay, filled with polystyrene foam balls, and made by burning. It has the characteristics of high raw material purity, uniform pore structure, low thermal conductivity, low heat capacity, high strength, and high dimensional accuracy.
