Vermiculite is very universal mineral. It is clean, with no fragrance, odorless and mold-resistant. It has a remarkable ability to expand many times during heating. This property is known as exfoliation (peeling, flaking).
The use of vermiculite is very broad. It can be used in many applications, most of which require exfoliated vermiculite. Once the vermiculite has undergone exfoliation, it is sterile because of the high temperature during production.
Unlike similar minerals, vermiculite does not contain asbestos or fibrous carcinogenic particles.
