Shivam Insulation Bricks


In ceramic industries, cost of fuel is about 40 to 45% of total cost of product and cost of fuel is increasing high & high in every month. Cost of product can be reduced by energy conservation. Using good quality & insulation materials in kiln can save energy. Insulator brick & blocks should have high porosity, low bulk density, high cold crushing strength (CCS), low permanent linear changes after firing (PLCR) and low thermal conductivity.

Shivam Hot face insulating bricks and blocks “HFK – 451” and high alumina porosint “P – 451” have all above properties. Our products give very good result in roller hearth & tunnel kiln.
