Evonik Bed Support Ball Products
Durocel 222 is a highly inert vitrified silicon/aluminium oxide composite ceramic. Used in a variety of adsorptive and catalytic applications, Durocel 222 is highly resistant to mechanical stress and thermal shock.
Durocel 235 is ideal for use in applications and catalytic processes demanding the highest level of protection against unwanted chemical reactivity and contamination and also ideal in those applications sensitive to silica. Durocel 235 is fired to high temperature during manufacture to create a low porosity material eliminating risk of shrinkage. Resulting physical characteristics yield excellent resistance to thermal and mechanical shock and abrasion. High chemical purity and mechanical integrity result in one of the most inert support media available.
All Evonik inert support materials are tested routinely to ensure consistent properties. With compositional and physical testing, Thermal shock, rapid depressurisation and impact tests are conducted.
