Product Description

Our high quality perlite, which is naturally occurring siliceous rock, can be safely used in construction applications, horticultural applications and industrial applications. Its unique internal structure consists of numerous tiny closed air cells surrounded by a large exterior irregular surface. Expanded Perlite is ultra-lightweight, inert, sterile, permanent, incombustible, asbestos- free, non-toxic, rot and vermin proof and has a neutral pH. Its internal closed air-cell structure resists thermal transmission giving Perlite its inherent insulating properties. Its extremely large, open surface area offers benefits in other areas such as horticulture and filtration. Because of perlite's outstanding insulating characteristics and light weight, it is widely used as a loose-fill insulation in masonry construction. In addition to providing thermal insulation, perlite enhances fire ratings, reduces noise transmission and it is rot, vermin and termite resistant. Perlite is also ideal for insulating low temperature and cryogenic vessels. Industrial applications for perlite are the most diverse, ranging from high performance fillers for plastics to cements for petroleum, water and geothermal wells. Other applications include its use as a filter media for pharmaceuticals, food products, chemicals and water for municipal systems and swimming pools. In horticultural applications, perlite is used throughout the world as a component of soil less growing mixes where it provides aeration and optimum moisture retention for superior plant growth. For rooting cuttings, **0% perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems.
