Vermiculite insulation board, commonly known as insulation board or refractory board, is a new type of insulation material. Vermiculite insulation board is a board made by hot pressing or cold pressing expanded vermiculite and a certain amount of adhesive.
Vermiculite insulation board has the characteristics of insulation, thermal insulation, and fire prevention. Vermiculite insulation board can be used in fireproof door cores, fireplace linings, and wall materials.
Vermiculite insulation board is a new type of inorganic material, mainly made of expanded vermiculite as the main raw material, mixed with a certain proportion of inorganic binder, and processed through a series of processes to form a board with high temperature resistance, fire resistance, green environmental protection, thermal insulation, sound insulation, and no harmful substances. Even when heated to 1200 ℃, it does not produce gases that are harmful to human health, and its combustion performance reaches Class A.
In China, vermiculite insulation board is still in its infancy stage, mainly exporting raw materials of vermiculite, while finished products are rarely used domestically. However, in recent years, the demand in the domestic market has gradually increased. Vermiculite insulation board has been widely used in developed countries such as the United States, the United Kingdom, and France since the 1980s.
Non combustible, non melting, and high temperature resistant, due to the fact that vermiculite insulation board is the main raw material for vermiculite, inorganic materials do not contain carbon elements and do not burn. Its melting point is 1370-1400 ℃, and the maximum operating temperature is 1200 ℃.
