Perlite

Perlite 1 .Perlite ore includes perlite, obsidian and pitchstone 2. widely used in oxygen manufacturer and freezer

Perlite:

Description:Expanded  Perlite is siliceous volcanic glass engendered from volcano eruption, it is named for its distinctive concentric cracks that is similar as pearls. Perlite ore includes perlite, obsidian and pitchstone. After heating to high temperature, perlite expandes into the new style light weight material. Its non-toxic, tasteless, fireproof, heat insulating and sound absorptive, and also with low heat conduction coefficient, stable chemical property and application in wide temperature scale ect.

Expanded Perlite's Applications:

It is widely used in oxygen manufacturer and freezer as well as insulating layer

in transporting liquid oxygen and hydrogen.

It can be used to filter liquor, oil, medicine, food and dirty water.

It can be used as filling and dilating agent in rubber, painter and plastic, etc.

It can be used as catalyst in explosives.

It can be used to absorb floating oil.

It can be used in agriculture and gardening to improve the soil and withhold water and fertilizer.

It can be mixed with different adhesive to make templates of different sizes and functions.

It can be used as in large volume as insulating layers in industrial smelting
