We are engaged in offering a range of high quality Insulating Castables that are designed for excellent consistency in density and with higher strengths. Used as backup layer in process industries and hot face layer in petrochemical industry, these insulating castables have low density and low thermal conductivity that help in conserving heat energy and reduce fuel costs. Insulating castable is an ideal unshaped refractory product.
