On March 16th, after nearly seven years of unremitting research by the scientific research team, Yanshan Petrochemical successfully produced metallocene polypropylene products. This is the first time that successful implementation of metallocene polypropylene has been realized in China's industrialized continuous production facilities. It marks that Yanshan Petrochemical has become a domestic The first metallocene polypropylene continuous production company.
According to Yanshan Petrochemical researchers, metallocene polypropylene is a polypropylene product produced using metallocene catalysts. At present, all domestic continuous polypropylene industrial plants use Ziegler-Nata catalyst to produce polypropylene. Metallocene polypropylene Compared with the traditional catalyst system, the polypropylene product has a more regular molecular chain, a better product appearance, good transparency, lower volatile matter and precipitate content, and more cleanliness. It can be widely used in spinning, medical, food packaging and other fields. Currently, only a few large international petrochemical giants such as Exxon Mobil, Basel, and Mitsui have truly commercialized metallocene polypropylene products. There is no precedent for domestic companies to form a potential gap in the metallocene polypropylene market. Technology has also become the focus of development in the international polypropylene industry.
As one of the earliest factories in China, one of the largest synthetic resin manufacturers, Yanshan Petrochemical attached great importance to the industrial development and production of high-end polyolefin resins. Since 2011, the company has cooperated with domestic research institutes and established a Several people's research teams have initiated research and development and technological breakthroughs in the field of metallocene polypropylene. In the past seven years, after nearly 100 laboratory tests and three industrialized production studies, Yanshan Petrochemical's scientific research team has continued to learn from experience and learn lessons. Optimize and improve the process plan, overcome many production problems, and finally fully open up the production process, achieve continuous and stable operation of the device, and successfully produce qualified metallocene polypropylene products. The success of this trial production has filled the production of domestic continuous metallocene polypropylene. The blank achieved a zero breakthrough.
