Yangzi Petrochemical industrializes the production of metallocene polypropylene

On November 16, Yangzi Petrochemical successfully industrialized the first industrial production of metallocene polypropylene new product mPP using a metallocene catalyst independently developed by Sinopec H-Y45-S
。 After testing, the performance indicators of the product meet the design standards, and the operating condition of the device is good
.

"The company is committed to the high-end differentiated research and development of polyolefin products, and the scientific research team has achieved a breakthrough in the production process of metallocene polypropylene and the continuous and stable operation of the product on the pilot plant, becoming the second enterprise
in China to achieve continuous production.
" Yang Liu, director of the Synthetic Resin Research Institute of Yangtze Petrochemical Research Institute, introduced
.

In order to ensure the success of the first industrial production, Yangzi Petrochemical established a technical research team for the production of metallocene polypropylene products, and determined the process operating conditions of metallocene
catalysts.
In the production process, internal and external operators work closely together, strictly implement the production plan, pay close attention to key process parameters, increase the frequency of inspection, and ensure the realization
of each production goal.

Metallocene polypropylene products have narrow relative molecular mass distribution, low melting point, good spinnability, high transparency and gloss, and can be used in spinning, non-woven fabrics, food containers, packaging, thin-walled containers, medical and health and other fields, which is an important direction for the high-end development of
polypropylene industry.
For a long time, this technology has been mainly monopolized
by large foreign petrochemical enterprises.
At present, China's metallocene polypropylene production technology has achieved new breakthroughs, related catalyst development has also achieved a number of important results, metallocene polypropylene production level is gradually approaching the world's
advanced level.
