Catalyst DQS Series

Catalyst DQS Series

Overview of product performance and technical characteristics

The catalyst DQS Series is a set of efficient spherical propylene polymerization catalysts developed by Sinopec Beijing Research Institute of Chemical Industry. Thanks to an original carrier preparation technology with proprietary intellectual property rights, the catalyst DQS Series has better combined properties comparing with other like catalysts, suitable for the unit using continuous processes such as Spheripol, ST, Spheripol-II and Spherizone for producing homopolymer and anti-impact, random and ternary copolymer PP. The catalyst DQS Series is used for mainly producing high quality homopolymer and anti-impact and random copolymer PP. The catalyst DQC Series has a list of technical characteristics as below.

Narrow distribution of catalyst particle size and controllable and adjustable particle size;

Catalyst activity ≥5.5×104g﹒PP/g﹒cat (5L polymerizing pot, bulk polymerization for 2h at 70˚C,hydrogenation at 0.2Mpa);

Excellent hydrogen modulation balancing ability;

Excellent directional ability and adjustable polymer isotactic index;

Excellent copolymerization performance for producing high rubber content anti-impact copolymer;

Spherical polymer particle with good shape and less fine powder.
