Catalyst BCH

Catalyst BCH

Overview of product performance and technical characteristics

The catalyst BCH is an efficient Ti-series carrier type Ziegler-Natta ethylene polymerization catalyst, suitable for the units using slurry polymerization processes such as Mitsui slurry polymerization process for producing various injection, extrusion and blow molding high density PE. It has been applied in all the domestic units using Mitsui slurry low pressure ethylene polymerization process for long periods in the grades of 5000S, 5200B, 2200J, 5300E and 6100M, etc. The catalyst has a list of technical characteristics as below.

Catalyst activity ≥2.5×103g﹒pe/g﹒cat (2L polymerizing pot, slurry polymerization for 2h at 80˚C, the pressure ratio of hydrogen and ethylene: 0.28Mpa:0.45Mpa);

High hydrogen modulation sensitivity and controllable polymer MI value;

Excellent copolymerization performance;

High polymer bulk density, BD≥0.27g/cm3;

Excellent polymer properties.
