Wearing Resistant Plastic Refractory

Wearing resistant plastic refractory is made from corundum, silicon carbide, special grade bauxite raw materials, ultra micro powder, composite binders, additives and plasticizer are added into raw material. It has good plasticity, long storage time, and its strength increases with the raising of temperature, which ensures good mechanical strength and abrasion resistance.
