Norlite  Expanded Perlite 
As a Filler

Industrial applications for perlite are the most diverse, ranging from high performance fillers for plastics to cements for petroleum, water and geothermal wells.

Filter Media

Other applications include its use as a filter media for pharmaceuticals, food products, chemicals and water for municipal systems and swimming pools.

Additional applications include its use as an abrasive in soaps, cleaners, and polishes

Low Temperature Insulation

Perlite is also ideal for insulating low temperature and cryogenic vessels.

Perlite's outstanding insulating characteristics and light weight, make it an ideal for packing cold storage containers with insulation material

Perlite for Industrial Applications

Being lightweight, non-combustable, and insulating, perlite has been found to be useful in a wide variety of industrial applications. Perlite can safely be used over a wide range of temperatures.


Used for high temperature insulation, molten metal topping, cryogenic insulation, filtration, and lightweight fillers system and provides holding capacity for water and nutrients.

A variety of foundry applications utilizing perlite's insulating properties and high heat resistance.


 This same heat resistant property is taken advantage of when perlite is used in the manufacture of refractory bricks, mortars, and pipe insulation
