1.Product Introduction
Vermiculite board is produced through series of productive technologies, by compounding expanded vermiculite and inorganic macromolecule adhesive. Vermiculite has properties of nonflammable, heat preservation, heat insulation, sound absorption, Thermoregulation and innocuity. When heated, it is smokeless, nontoxic and tasteless. Vermiculite board contains no asbestos, it is a kind of pure natural and environmental material.
