About Us

• NON-ASBESTOS HIGH TEMPERATURE CALCIUM SILICATE INSULATION It is mixed with Xonotlite and renforced glass fibre with high service temp.(1050℃), good heat insulation, low bulk density, high strength, good durability and so on. Product Characteristics:  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 Laizhou Mingguang Thermal Insulation Materials ...ight, 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.
