Perlite insulation board has good insulation properties, good heat resistance, good acid and alkali erosion resistance,non-toxic

Characteristic:
Perlite insulation board is one of the thermal insulation refractory products, mainly chemical composition is perlite. According to different binder, Expanded  perlite insulation board can be classified cement combined with perlite insulation board, soluble glass combined with perlite insulation board, phosphate with perlite insulation board etc. Following is the physical index of Cement combined with expanded perlite insulation board. It has good insulation properties, good heat resistance, good acid and alkali erosion resistance, non-toxic, harmless, moisture absorption rate is very small, long-term preservation and non-degenerate when used after long term. The Expanded perlite insulation brick has a wide using temperature range. It not only can be used as a medium temperature thermal insulation material, but also as an insulation material. The maximum operating temperature is about 1000 degrees, the minimum temperature is to -200 degrees.

Application:
It is widely used in the thermal equipment, refrigeration equipment and refrigeration engineering adiabatic of metallurgical, chemical, electrical, construction, defense industries and other departments.
