D235 is an Inert Alumina ball ideal for the use in application and catalytic processes demanding the highest level of protection against unwanted chemical reactivity and catalyst contamination. Also ideal for those applications sensitive to silica.

The minimal silica content allows D235 to be chemically inert to prevent fouling of your catalyst bed or coating of downstream equipment.

It’s a high Alumina balls which is best for applications with olefin processes, such as ethylene dryers.
