17% Ceramic Ball
Introduction
The 17 Support Media is equal to Denstone® 57 Support Media.
They are the most widely used support media in the world because of their
excellent consistence and reliability. Products to these specifications are
manufactured from very high quality chemical-porcelain clay materials, which
has quite excellent stability, high mechanical strengthand resistance to
thermal shock, This makes them all ideal choice for support of all types of
catalyst.
