1. Product specification

Expanded perlite insulation board&perlite fireproof brick is a kind of product with characteristics of non-toxic, odorless, non-combustibility, corrosion resistance, acid-base resistance, insulation, sound and thermal insulation and honeycomb interior structure. It is a white or light-colored superior thermal insulation material made through smashing acid volcano glass lava, screening to a certain granularity, preheating again, and sintering under high temperature of 1400°C. And it can be compounded with different adhesive into hydrophobic perlite insulation board, perlite sound absorption board, partition board, fire proof board, etc.
