Vermiculite is a mineral formed of certain basaltic minerals, essentially by hydrated aluminium and magnesium silicates, somewhat similar to Mica.

Vermiculite is a raw material used in friction materials due to its low abrasiveness, high thermal resistance, incombustibility and low chemical reactivity.

It is a safe alternative to replace asbestos. It can be used for the production of many different insulations, e.g. in exhausts and joints; and also as functional filler in paints. Another important application is in filters for many kinds of liquids. 

We have Crude and also Exfoliated Vermiculite qualities in different particle size distributions.
