CORROREF™ ACID PROOF / ANTI ACID BRICKS
CORROREF™ brand is manufacturing of Acid proof / Anti Acid bricks in different thicknesses as per Indian Standard IS 4860:1968 and ASTM C279 & DIN Standard with the help of Dry Process and are used as per the requirement. Our Bricks can resist highly concentrated acid, low water absorption, highly mechanical Strength, etc. CORROREF™ backed by more than 15 years of Acid resistance bricks making experience. These are fine-ground and specifically formulated for density and strength and fired at over 1200ºC. This process results in bricks that resist virtually all corrosive liquids and gasses, expect for acid fluorides and strong hot caustics.
