4. Characteristics and uses
This product is a new type of external electron donor for olefin polymerization. Due to its unique and excellent performance in olefin polymerization, it greatly improves the crystallinity, isotacticity and apparent density of polyolefin products; it is used as an electron donor for production The resulting polypropylene has the characteristics of high crystallinity and low melt flow rate, and is a strong electron donor. It can be used alone or paired with other electron donors to adapt to the production of different grades of polypropylene; when used in conjunction with a variety of catalysts, the performance and efficiency of the catalyst can be fully utilized.
