    expanded vermiculite

    Vermiculite is an entirely and naturally occurring mineral, similar to mica, that is sold both in its natural state and by exfoliating the core. Exfoliation is the term used to describe the expanding process raw vermiculite goes through under extreme heat, rendering the material naturally layered, perfectly suited for trapping air and moisture. It does not create any waste by products during processing and is inert, non-toxic, fire resistant and is capable of holding many times its weight in water.
    It has a wide range of uses in the horticulture industry as well as a variety of industrial applications from insulation to filler in the plastics industry.

    Horticultural Uses

    Vermiculite has properties that make it an ideal soil additive for horticultural purposes. In its expanded form, the mineral improves soil aeration and provides excellent moisture retention. Horticultural vermiculite is sterile, non-toxic, odorless and permanent. It does not deteriorate, mold or rot and it typically maintains a neutral 7.0 pH level.

    Commercial Uses

    In addition to its horticultural and agricultural uses, vermiculite is used extensively by the commercial and home construction industries. The mineral is an important additive to everything from gypsum plaster to acoustic and soundproofing materials. It is used in insulation and for fireproofing as well as for packing, filtration, and absorption. It is added to cement, paint, sealants and dozens of other materials for countless industrial applications.
