Use
In the construction and manufacturing fields, it is used in lightweight plasters, concrete and mortar (masonry), insulation and ceiling tiles. It may also be used to build composite materials that are sandwich-structured or to create syntactic foam.
In horticulture, perlite can be used as a soil amendment or alone as a medium for hydroponics or for starting cuttings. When used as an amendment it has high permeability / low water retention and helps prevent soil compaction.
Perlite is an excellent filtration aid and used as an alternative to diatomaceous earth. The popularity of perlite usage as a filter medium is growing considerably worldwide. Perlite filters are fairly commonplace in filtering beer before it is bottled.
Perlite is also used in foundries, cryogenic insulation.
Perlite is a useful additive to gardens and hydroponic setups.
Perlite has a neutral PH level.
It contains no toxic chemicals and is made from naturally occurring compounds found in soil.
Perlite is directly comparable to another mineral additive called Vermiculite. Both have overlapping functions and help with soil aeration and seed starting.
