Cryogenic Perlite

Cryogenic Perlite, also known as expanded perlite sand, for thermal insulation in low-temperature devices, is a product obtained by selecting small particles of mineral sand and heating them with natural gas as a heat source in a vertical shaft kiln. The reinforced product is sprayed with organic silicon on the surface of expanded perlite to form a hydrophobic structure. The product quality meets the requirements of European classification standards

Main Characteristics

It has characteristics such as small capacity, low thermal conductivity, good ultra-low temperature insulation performance, good chemical stability, non flammable, non-toxic, odorless, and sound absorption.

Application Area

Deep cooling, low-temperature engineering insulation, industrial equipment, pipeline insulation, etc; Widely used in air separation equipment factories, such as oxygen production air separation units, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigerated transport vehicles, transport ships, etc. It has the advantages of reducing cold losses, energy and electricity consumption indicators, etc
