vermiculite fireproof board/brick
vermiculite fireproof board/brickItem Code / Model Number:
vermiculite fireproof board/brick
The Vermiculite boards are mainly made of expanded vermiculite and mixed with certain proportion of inorganic polymer adhesive. The boards have good function of not burning, heat insulation and preservation, sound insulation, moisture adjustment and without any harmful substance. Vermiculite board is not containing asbestos and smoke-free, non-toxic when it is been heated. They are nature, green, innovation construction materials.
