Lightweight Insulation Castable

Description

Lightweight thermal insulation castables refer to castables with low bulk density.

Lightweight thermal insulation castables have low bulk density, small thermal conductivity, and good thermal insulation performance, which can reduce the heat energy consumption of industrial kilns and also reduce the furnace lining. weight.
