---Expanded Perlite /100L Bag
Perlite's use in agriculture and horticulture is revolutionary, addressing the essential needs of modern sustainable farming and gardening. The science behind perlite's success in these fields lies in its physical structure, formed when volcanic glass is heated to a high temperature, causing the water content to vaporize and the material to expand. The primary role of expanded perlite in soilless growing mixes is aeration when added to peat moss, composts, coir and other water-holding aggregates. The porous surface of perlite provides room alternately for both air and water in the mixes each needed for vigorous root growth.
Perlite is a heat expanded, man made Perlite for use as a hydroponic growing medium. Perlite retains enough moisture for it to be suitable as a hand watered medium, but also has sufficient drainage to be used in a recycling drip irrigation system. Perlite is extremely lightweight and is suitable for use in a variety of growing containers pots, trays, bottom fed auto watering systems, etc.
---Expanded Perlite Application:
* Horticultural Applications
In horticultural applications, perlite is used throughout the world as a componet of soilless growing mixed where it provides aeration and optimum moisture retention for superior plant growth. Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and for peletizing seed.
* Construction Applications
Perlite is widely used as a loose fill insulation in masonry construction. Other construction applications include chimney linings, under-floor insulation, gypsum boards, paint texturing, ceiling tiles, and roof insulation boards etc.
* Industrial Application
Ranging from high performance fillers for plastics to cements for petroleum,water and geothermal wells
