Metallocene polypropylene industry test made a breakthrough

Sinochem News News on November 4th, Harbin Petrochemical Company successfully produced more than 10 autoclaves of metallocene ultra-high-melting index polypropylene products, marking the company’s joint development of metallocene ultra-high-melting index polypropylene with the Institute of Petrochemical Industry A major breakthrough was made in industrial trials, and the first domestically-made catalyst was successfully used to produce a series of ultra-high melt fluidity metallocene polypropylene products in a batch bulk polymerization unit

Metallocene ultra-high melting index polypropylene has the characteristics of narrow molecular weight distribution, excellent impact strength and toughness, and is well compatible with many other resins.

Metallocene polypropylene needs to be produced using metallocene catalysts

At the beginning of 2021, on the basis of metallocene transparent polypropylene product experiment, the company and the Petrochemical Institute once again cooperated to start the industrial experiment of a new type of metallocene ultra-high melting index polypropylene

During the trial production process of the device, the management and technical personnel and staff at all levels put their full effort into continuously adjusting the process indicators according to the production situation, discussing and solving the unexpected problems in the trial production process in depth, and further exploring the best production control conditions of the device to obtain The valuable experience has provided a guarantee for adding new products to the product sequence of the polypropylene plant
