calcium silicate board refractory material

calcium silicate board refractory material > good durability, can bear high temperature within the limit of continuous heat load, > low thermal conductivity, in the whole range are used with unmatched adiabatic performance. > light weight, high strength. It is the highest in these hard thermal insulation products. >better durability, use for a long time without powder. >construction with ordinary carpenter applicability, tools can be optional cut products. > used safety, hygiene. Excluding asbestos, sulfur, chlorine such poisonous substances. > fear water, but after drying also can be used.
