Acid Resistant Castable is a premium refractory material formulated with high-purity aggregates and specially engineered binders to withstand strong acid corrosion and harsh chemical conditions. Compared with traditional acid resistant bricks, this castable allows seamless lining, flexible installation, and complex shape construction, significantly improving lining integrity and corrosion resistance.
The material features high density, low porosity, excellent acid resistance, and high mechanical strength, making it suitable for monolithic linings in chemical processing equipment, flue gas systems, and industrial vessels. It effectively reduces leakage risks, shortens installation time, and lowers overall maintenance costs.
Our acid resistant castable is produced under strict quality control and complies with international refractory standards. Customized formulations are available to meet specific operating temperatures, acid types, and service conditions.
