Factory Low price 1-3mm 3-6mm Horticulture Soil Improvement Used Expanded Perlite
1. Description: Perlite is siliceous volcanic glass engendered from volcano eruption, it is named for its distinctive concentric cracks that is similar as pearl's. Perlite ore includes perlite, obsidian and pitchstone. After heating to high temperature, perlite expands into the new style light weight material. It's non-toxic, odorless, fireproof, heat insulating and sound absorptive, and also with low heat conduction coefficient, stable chemical property and application in wide temperature scale, etc.

Expanded perlite for horticultural
In horticultural applications, perlite is used in expanded perlite ,which is used as a component of soilless growing mixes as it provides aeration and optimum moisture retention for superior plant growth. For root cuttings, 100% perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems. Other benefits of horticultural perlite are its neutral pH and the fact that it is sterile and weed-free. In addition, its light weight makes it ideal for use in container growing. Other horticultural application of perlite includes as: fertilizer , herbicides and pesticides carriers and for seed pelletizing. Horticultural perlite is as useful to the home gardener as it is to the commercial grower. It is used with equal success in greenhouse growing, land-scaping applications and in the home in house plants.
Construction industry:
