Dingjide Petrochemical
Propylene polymerization catalyst
DJD-Z series
DJD-Z series catalysts are the fourth generation of granule form Ziegler-Natta catalysts, have characters of high activity, good hydrogen response and low polymer fines. Can be used to produce full range PP grades in Unipol, Novolen, Innovene, Hypol and SPG PP production technologies.
