Alumina filler ball are high performance inert ceramic balls widely used as tower packing media, catalyst support, mass transfer & heat transfer media in petrochemical, chemical, environmental and industrial plants. With excellent high temperature resistance, corrosion resistance and mechanical strength, they ensure stable operation in demanding environments.
characteristic
High Purity Alumina Composition (≥92% / ≥99%) – superior mechanical strength.
High Temperature Stability – stable under extreme industrial conditions.
Corrosion Resistance – resistant against strong acids & alkalis.
Low Absorption & High Density – consistent packing performance.
Optimized Ball Shape & Size – improves gas/liquid distribution in tower media.
