Perlite
Environmentally Friendly, Ultra-Lightweight Aggregate.
Expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 6mm in size. It is inorganic, inert, neutral in pH, biologically stable and has no asbestos content.
It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C. It also has a highly adsorbent surface and a very low bulk density which makes it an ideal carrier or low cost filler for many compound formulations.

Applications
Cryogenic
Non-combustible ultra-lightweight mineral aggregate with excellent insulation & adsorption properties
Castables
Perlite insulation is used in high temperature applications in the steel and foundry industries such as ladle topping, hot topping and risering.
Construction
Due to its high insulating qualities and versatility expanded perlite is widely used in the construction industry for masonry and other build types.
Absorbent
Silvaperl’s exfoliated vermiculite and expanded perlite are absorbents and carriers. Each of these unique minerals have their own characteristics
Cavity Fill
Silvapor coated expanded perlite is a hydrophobic insulating aggregate. This water repellent, non-flammable, loose-pour insulant improves the thermal performance on masonry walls and floors.
Landscaping
Expanded Perlite is suitable for a range of landscaping applications such as green roof construction, golf green renovation and construction, planters, drainage.
