Dingjide Petrochemical
Efficient catalyst for ethylene polymerization
DJD-PES-B
DJD-PES-B polyethylene catalyst is specially used in Unipol ll gas phase fluidized bed process and serves as an efficient polymerization catalyst for the production of bimodal polyethylene. The catalyst morphology is a near-spherical. The catalyst has excellent copolymerization performance and hydrogen modulation sensitivity. The polymer has excellent physical and mechanical strength and excellent processing properties, making it suitable for the production of high-end PE80 and PE100 pipe materials.
