Expanded Perlite Powder is an amorphous volcanic glass/ alumina–silicate rock that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. Perlite has the unusual and critical property of expanding rapidly when  heated to 1400–1800 F (760–980 C) to create a product termed expanded perlite.

Expanded Perlite Powder Being porous in nature, perlite can be filled with various materials which indeed makes it an excellent resistant to fire and shows improved thermal property.  The excellent thermal conductivity of expanded perlite. Perlite is inorganic material. Perlite loose fill insulation offers excellent fire resistant and thermal properties . Perlite is light weight and pours. Expanded Perlite is ultra-lightweight, inert, sterile, permanent, incombustible, asbestos- free, non-toxic, rot and vermin proof and has a neutral pH.

Expanded Perlite Powder is an amorphous, highly porous, granular material of volcanic origin. Its two main components are Al2O3 & SiO2. The low density and high porosity are two properties of expanded perlite. The application purposes other beneficial properties of temperature stability. The specific type of perlite is actually used in practice for the insulation of liquid gas storage tanks.

Expanded Perlite Powder the major perlite markets are for expanded perlite. Perlite is an amorphous volcanic glass/ alumina–silicate rock that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. Perlite has the unusual and critical property of expanding rapidly heated to 1400–1800 F (760–980 C) to create a product termed expanded perlite.

Expanded Perlite Powder is an amorphous volcanic glass/ alumina–silicate rock that has a relatively high water content, typically formed by the hydration of obsidian. Uses of perlite include masonry construction, cement and gypsum plasters, and loose fill insulation. Perlite is also used in pharmaceuticals and municipal swimming pool water filtration as well as an abrasive in polishes, cleansers and soaps.
