23-26% Ceramic Balls
Product Description
Packing Mall Ceramic Ball 23%-26%, the main effect is to increase the distribution of gas or liquid,support and protection of activity catalyst.Packing Mall Ceramic Ball 23%-26% one of the new media in the industry with unmatched impact resistance, thermal shock, crush strength and survivability. It is manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, this makes them all idea choice for support of all types of catalyst.
Typical application
1. Widely used support media in the world because of their excellent consistence and reliability.
2. Manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
