INSULATION CASTABLES & GUNNING MIXES
VITCAST 1300INS & GUN MIX
VITCAST 1400INS & GUN MIX
Medium weight insulation castable which has high strength combined with low density and good insulation properties. Used for kiln floors, soaking pit side walls, sub hearths in higher temperature applications, cooler zones and flues /stacks where abrasion resistance is required as well as insulation.
Medium weight insulation castable with lower iron content and higher working temperature. Can be used in the centre of lids and doors where the perimeter is cast in a high strength material.
