Dingjide Petrochemical
Propylene polymerization catalyst
DJD-B series
DJD-B series catalysts are the fourth generation of spherical 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 Spheripol and Spherizone PP production technologies.
