High Alumina Support Balls are widely used as catalyst bed support media in refining, petrochemical and gas applications, where low silica content or high alumina is required. With characteristics of high hardness, high density, high crush strength, excellent thermal properties, etc.Our ball is your smart choice in catalyst and adsorbent bed support media because of the high raw material, controlled processing and the most consistent properties. These balls are equivalent to Destone99.
Available Sizes: 1.5mm, 3mm, 6mm, 10mm, 13mm, 16mm, 19mm, 25mm, 30mm, 38mm, 50mm, 75mm, 90mm, 120mm
