Recently, Maoming Petrochemical Research Institute and cooperative units carried out a pilot test for the application of domestic metallocene polypropylene catalysts, and carried out a polymerization test in a 12-cubic-meter bulk tank reactor, producing a total of 12.
7 tons of pilot-scale products

It is reported that the metallocene polypropylene catalyst system has a single catalytic active center.
The metallocene polypropylene produced has the advantages of good spinnability, high transparency and gloss, and low precipitation.
The products are mainly used for spinning, non-woven fabrics, staple fibers, etc.
, food containers, packaging, thin-walled containers, medical and health and other fields

Over the years, this technology has been monopolized by several large foreign companies, and the metallocene polypropylene catalysts used in China are all imported

In order to promote the transformation of the domestically developed metallocene polypropylene catalyst system, Maoming Petrochemical Company, Shanghai Chemical Industry Research Institute and Xiamen University, after years of joint research, successfully applied the catalyst developed by Shanghai Chemical Industry Research Institute in the pilot plant for the first time.
It is the first domestically produced metallocene polypropylene catalyst that has been successfully pilot-tested, marking the maturity of this type of domestically produced catalyst and laying the foundation for the future breakthrough in the localization of metallocene polypropylene technology
