Product Description

Another product that we supply is the castable refractories that are low density. These insulating castables pose very low thermal conductivity and are utilized for either high temperature face work or when used for a backup lining, which is found behind dense castables or brick work. Here, the insulating castables are able to decrease the lining's overall density or the cold face temperature. Their strength, which ranges from low to medium, is based on the fact that their density is low and is the main reason that they are not resistant to abrasion. They are most suitable where they do not have to stand up to much wear and tear.

1.Yaohua 1200INS & Gun Mix

Very lightweight backup insulation castable. Typically used between the outer casing and lining in boilers, flues / stacks and low temperature applications where a lightweight material is required.
