?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.
