Dingjide Petrochemical
Ethylene polymerization catalyst
DJD-PES-B
DJD-PES-B catalyst is a spheroid shape high-efficiency catalyst for the Unipol gas-phase fluidized bed PE production technology. Has characters of good copolymerization performance and hydrogen sensitive. Can be used to produce bimodal polyethylene, especially in high end PE80 and PE100 pipe grades. The polymer shows good mechanical and processing properties.
