Vermiculite

Vermiculite is a member of the phyllosilicate or sheet silicate group of minerals.

It has the unique ability to expand to many times its original volume when heated - a property known as exfoliation. The majority of applications call for vermiculite in its exfoliated form.

Vermiculite has a wide range of uses that take advantage of its remarkable attributes of resilience to fire, refractory nature, thermal and acoustic insulation properties, absorption capacity, low density and ease of handling.

Vermiculite is widely used in the construction industry, for horticultural applications, the automotive field, and for high temperature and industrial insulation uses.
