    Expanded Perlite

    ?

    ?

    ?

    ?

    Perlite softens when it reaches temperatures of 850-900℃.Water trapped in the structure of the material vaporises and escapes,and this causes the expansion of the material to 7-16 times its?
    original volume.The expanded material is a brilliant white,due to the reflectivity ot the trapped bubbles.Unexpanded("raw") perlite has a ulk density around 1100kg/m3,while typical expanded perlite has a bulk density of about 30-150kg/m3

    Perlite?uses
    In the construction and manufacturing fields,it is used in lightweight plasters ans mortars,insulation and ceiling tiles.
    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 filter aid.It is used extensively as an alternative to diatomaceous earth.The popularity of perlite usage in this application is growing considerably wordwide.Perlite filters are fairly commonplace in filtering beer before it is bottled.
    Small quantities of perlite are also used in foudries,cryogenic insulation,as a lightweight aggregate in mortar(firestop) and in ceramics as a clay additive.It is also used by the explosives industry.
