Introduction:

The 17 Support Media is equal to Denstone 57 Support media. The are the most widely used as catalyst 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 strength and resistance to thermal shock, this makes them all ideal choice for support of all types of catalyst.

Typical Application:

a) Widely used support media in the world because of their excellent consistence and
b) 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.

Warranty:

a) By National Standard HG/T 3683.1-2000
b) Offer lifetime consultation on problems occurred
