Lightweight clay insulating brick
Lightweight clay insulating brick is a high-performance lightweight thermal insulating refractory product, which is sintered at high temperature with high-quality soft clay as the main raw material. As a high-end lightweight variety of fire clay brick, it integrates dual properties of thermal insulation and refractory load-bearing, and is the core thermal insulation material for industrial furnace linings.primarily supplying the East Asian and Southeast Asian markets.
