DQC family catalyst uses the carrier which is creative and prepared
by a new process. Comparison with the similar catalyst, the
comprehensive performance is improved obviously.
1) Particle size distribution of catalyst is centralized, and the
particle size is controllable and adjustable.
2) Catalyst activity is more than 5.0X104 g-PP/g-Cat.(Condition: 51
reactor, polymerization temperature is 70℃, reacted time is 2
hours, distributed pressure of H2 is 0.2MPa.)
3) Excellent hydrogen responsibility.
4) The polymer has a good isotacticity, and the isotacticity index
5) This kind of catalyst has an excellent copolymerization
performance, and is suitable to produce the high rubber content
6) Polymer particle is spherical, and has good morphology, and less
This kind of catalyst is suitable to use in Spheripol-I process,
spheripol-II process and ST process. It is widely used to produce
homo-polymer, impact copolymer, random copolymer and three units
DQC301 catalyst has smaller particle size, ad is suitable to use in
single spheripol process and can be used to produce homo polymer.
DQC401 catalyst belongs to general type PP catalyst, is suitable to
use in single spheripol process, double spheripol process, ST and
gas phase process, can be used to produce homo-polymer, impact
copolymer, random copolymer.
DQC602 catalyst is suitable to produce impact copolymer and three
DQC family catalyst is widely used in Spheripol-I process,
spheripol-II process and ST process and is more than 30 suites
plants distributed in China and other countries. The products has
homo polymer, impact copolymer, ethylene-propylene random
copolymer, propylene-butene random copolymer, and
ethylene-propylene-butene random copolymer, and have a good
Packaging. Storage and Transport
DQC family catalyst is packaged in zinc-plated steel drums under
nitrogen protection, and contains 40 or 80kg every drum. In
transportation, the catalyst should be handled carefully avoiding
bumping, opening of cover or contacting with air. It should be
stored in a dry, clean and ventilated space out of direct sunlight.
