Chemical composition of expqanded vermiculite:

Usage

Calcium silicate boards

In the production of calcium silicate bound boards exfoliated vermiculite is added to a calcium silicate slurry, this is then dewatered by pressing or by using one of the Fourdriner/Magnani/Hatschek processes to form a flat board which is then heat cured under pressure (typically 10-15 bar) for periods up to 24 hours

General Building Plasters

Exfoliated vermiculite is used in both hand and spray applied general building plasters to improve coverage, ease of handling, adhesion to a wide variety of substrates, fire resistance, and resistance to chipping/cracking/shrinkage. Vermiculite can also be combined with other aggregates such as perlite to produce plasters.

Roof and Floor Screeds and Insulating Concretes

Exfoliated vermiculite (typically the finer grades) can be added at site to portland cement and other aggregates, rheological aids and water to produce roof and floor concrete screeds or lightweight concrete which have the benefit of being lightweight and insulating. In many cases vermiculite based roof screeds are often used in conjunction with other insulation materials such as polystyrene board to form a total roofing system.
