Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. The green community recognizes perlite-enhanced products—like insulation—as a high-performance solution drawn from a natural material of nearly unlimited supply throughout the world.
The present invention provides an expanded perlite for low temperature thermal insulation, which reduces conductivity by minimizing porosity and gaps between the particles, and can increase carrying capacity for liquefied gas by reducing the thickness of the insulation structure through reduction of boil-off gas (BOG), such as LNG.

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.
