An inert, non-flammable mineral with many applications.


Vermiculite is a hydrous mineral. It is a pure, natural product. In order to make the raw vermiculite suitable for use, the coarse lumps are ground smaller. What’s more, it is heated above 900 degrees. This produces a very light, non-flammable, inert, highly heat-resistant material.
