WELCOME TO THE VERMICULITE ASSOCIATION
Vermiculite is a unique, naturally occurring, inert laminar mineral that finds use in many construction, industrial, home, agricultural and garden products and systems.
Chemically a hydrated magnesium aluminium silicate, vermiculite exfoliates (expands) when heated to form a ultra lightweight aggregate. This product is non-combustible, compressible, highly absorbent, nonreactive and it may also have high cation exchange capacity.
Exfoliation occurs when vermiculite's interlayer water is transformed into steam. The pressure of the steam forces the silicate layers in the mineral apart and the flake forms an elongated concertina-like particle up to 30 times its original thickness.
Vermiculite is one of the safest and most unique minerals in the world. Readily available vermiculite is available in a number of different size fractions and in chemical dispersions.
