DQ family catalyst is a new generation spherical high -efficiency
1)Catalyst and polymer particle is spherical, and can be adjustable
in a large scope.
2)Catalyst activity is more than 4.5X 104 g-PP/g-Cat. (Condition:
51 reactor, polymerization temperature is 70℃, reacted time is 2
hours, distributed pressure of H2 is 0.2MPa.)
3)Polymer has a good isotacticity, and isotacticity index is
4)Polymer has high bulk density.
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, and random copolymer.
DQ-III catalyst belongs to general type PP catalyst, can be used to
produce homo-polymer and co-polymer, and applied in single
spheripol and double spheripol process.
DQ-IV catalyst has a smaller particle size, and suitable to produce
homo-polymer, especially suitable to produce BOPP product, and be
used in single spheripol process.
DQ-V catalyst has an excellent hydrogen response, and mainly to
produce high-speed BOPP.
DQ-VI catalyst has a higher activity in later stage of
polymerization, and is mainly used in double spheripol process, and
can produce high impact PP.
Packaging. Storage and Transport.
DQ 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.
