Product Description
Product Details
Introduction
Dicyclopentyl dimethoxy silane can greatly improve the crystallinity, isotacticity and apparent density of polyolefin products. The produced polypropylene has the characteristics of high crystallinity and low melt flow rate, and is a strong electron donor. It can be used alone or in combination with other electron donors to adapt to the production of different grades of polypropylene.
It is a colorless transparent liquid under normal pressure, with a boiling point of 118℃/9mmHg and a flash point of 94℃ (closed cup). It has a special fragrance, is protected by nitrogen, and has stable performance when stored in a sealed container. It is easily hydrolyzed with water or moisture.

Application
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; the polypropylene produced with it as an electron donor has the characteristics of high crystallinity and low melt flow rate, and is a strong electron donor. It can be used alone or in combination 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.
