1.Vermiculite board is a non-combustible board in which the unique cellular structure of vermiculite is
maintained and controlled by a pretreatment process. This gives excellent thermal insulation properties
with dimensional stability at high temperatures. It is used extensively for the fire protection of structural
steel elements in buildings to provide up to 240 minutes fire protection. It may also be used to protect
sheet metal ducts and for the construction of smoke extract ducts.

3. Application:
The characteristics of vermiculite board: not burning, not melt, high temperature resistant, because of the monolayer slab with expanded vermiculite as main raw materials, inorganic materials without carbon, don't burn.Its melting point is 1370 ~ 1400 °C, the highest temperature is 1200 degrees Celsius, and constant heat preservation.Chen xing industrial production of vermiculite stone is made of high quality of xinjiang no asbestos vermiculite is made and be become, non-toxic, smoke-free, green environmental protection, inorganic materials without carbon and sulfur elements, will not born CO2 and SO2 these effects of atmospheric air, also won't cause harm to human body.
Vermiculite board is widely used abroad to construction, shipbuilding, metallurgy, electric power, aerospace and other fields, the concrete application in: 1, fireproof doors core;2, senior kitchen utensils and appliances, furniture,3, hull plate;4, fire escape, and ventilation systems;5, shopping malls, Banks, libraries, hotels, restaurants, entertainment venues, senior housing, residential, etc.;6, kiln heat preservation;7, fireplaces, heat preservation;8, insulation materials used in industry.
