Perlite is a by acidic volcanic glassy lava through crushing, preheating, roasting expansion made having a porous structure, white, granular loose material with a non-toxic, tasteless, non-burning, non-corrosive, low thermal conductivityand reliably chemical stability, good filling flowability and low bulk density.

Perlite expanded perlite (Ultra Low Thermal Engineering) is a powder selected advice PELLETS ores in a vertical shaft kiln to natural gas as a heat source, heating the expansion of the product obtained, wherein the reinforced product is in the expansion the perlite surface coating silicone form a hydrophobic structure.

Perlite purposes: mainly used in cryogenic thermal insulation of cryogenic engineering, industrial equipment, and pipe insulation; widely used in home and abroad, large, medium and small air separation plant, oxygen plant air separation unit, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigerated transport, travel, etc., to achieve design capacity, reduce cold loss, reducing energy power consumption indicators.
