Application
Widely used in the insulation layer of industrial kilns, such as glass kilns, hot air furnaces, etc., to improve the thermal insulation performance of kilns and reduce energy consumption. It is also suitable for other industrial fields that require light weight, high temperature resistance and good thermal insulation performance.
