PERLITE is a type of volcanic glass containing combined water. When the crude rock is crushed and heated around 900⁰C, the combined water vaporizes and the perlite expands 20 to 30 times its original volume creating countless tiny air cells which accounts for its lightweight and excellent thermal insulation properties for high and low temperature insulation and cryogenic application.

Advantages and Benefits

 ·         Chemically inert; non-toxic

·         Free flowing which completely fill in any storage shapes tank

·         Rot vermin and termite resistant

·         lightweight and less expensive than any other insulation.

Loose-fill Insulation for low Temperature and Cryogenic Application            

Liquefied gases having low storage temperatures, therefore creating a demand for storage facilities capable of economically reducing evaporation losses and prevent erratic temperature change which cause explosion. A large majority of the vessels are of double construction and the annulus is filled with expanded perlite.
