Product Description
Inert Alumina Ceramic Balls are also called catalyst support media, ceramic balls is a high-quality alumina wear-resistant particle material, with alumina as the main component, and made of very high-quality chemical ceramic clay material.
It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the erosion of organic solvents such as acids and alkalis, and can withstand temperature changes in the production process.

Product Application
Inert Alumina Ceramic Balls can be widely used in catalysts, reactors, and adsorbents , tower packing.
Inert ceramic balls are widely used in the oil refining industry, petrochemical industry, and refining industry as catalysts or support
materials for absorption layers.Due to its excellent chemical resistance, it is suitable for olefin process applications where
polymerization problems exist, such as ethylene dryers
