Description
Mullite-silica filler ZMKR-0.8 is a lightweight refractory thermal insulation material based on a mullite-silica porous structure, designed for the manufacture of insulating and structural-insulating concretes, masses and mixtures operating at high temperatures. The material combines high thermal stability with reduced density, providing effective thermal insulation and reducing the weight of the lining of thermal units.
