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.
Also used in foundries and cryogenic insulation.
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.
It is a useful additive to gardens and hydroponic setups, with a neutral PH level, containing no toxic chemicals and made from naturally occurring compounds found in soil.
Directly comparable to Vermiculite, sharing overlapping functions to help with soil aeration and seed starting.
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.
