Specifications

Non-asbestos high-temp calcium silicate heat insulation refractory
Good durability
Low thermal conductivity
High strength

Non-asbestos high-temp calcium silicate heat insulation refractory 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 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.
