The Chemxin 23 Support Media is equal to Denstone® 2000 Support Media. It is one of the new media in the industry with unmatched impact resistance, thermal shock, crush strength, andsurvivability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellentstability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
