Asbestos-free Calcium Silicate Insulation Board

It is mixed with xonotlite and reinforced glass fibre with high service temp. (1050°C), good heat insulation, low bulk density, high strength, good durability and so on. Product Characteristics: 2 Good durability, can bear high temperature within the limit of continuous heat load. 2 Low thermal conductivity, in the whole range is used with unmatched adiabatic performance. 2 Light weight, high strength. It is the highest in these hard thermal insulation products. 2 Better durability, use for a long time without powder. 2 Construction with ordinary carpenter applicability, tools can be optional to cut products. 2 Used safety, hygiene. Excluding asbestos, sulfur, chlorine such poisonous substances. 2 Fear water, but after drying also can be used.
