Quick Details
Specifications
In order to effectively reduce the heat loss of boiler and raise the volume stability of thermal insulation material, the light insulating castable has been developed, which exhibits such features as good construction performance high volume stability and high strength.
We can make most of castable to zero baking castable with free of maintenance and baking, save oven cost and time. This castable is one. you can send email to hotmail: jznem-sunny.
