Product Introduction
Product Details
Anorthite thermal insulation brick is a new type of thermal insulation material developed successfully in recent years. Its microporous structure and low thermal conductivity are good materials for low temperature thermal insulation. Some performance indicators (typical values) are as follows: bulk density 0.48 g/cm3 . The compressive strength is ≥ 1.0MPa, the average thermal conductivity is 0.09w/mk, and the reburn line variation is ≤ 0.3.
