The Yangzi Petrochemical Research Institute successfully used a polypropylene pilot plant and successfully developed high-speed atactic polypropylene in early August. Low-flow atactic polypropylene grades are on the market. However, due to the difficulty of production, high-flowing random brands have less market supply and higher prices, the country mainly relies on imports. Some of the high-flowing random labels obtained through degradation also limit their use in places where food and environmental requirements are high because of their unavoidable taste. Yangzi Petrochemical Polypropylene Pilot Plant adopts new production process conditions and corresponding catalyst system. Because the product is directly obtained through polymerization, it is different from the product obtained by peroxide degradation, and the high flow random grade special material produced is wider. Relative molecular mass distribution, good performance, no odor. The special material can meet the requirements of users to shorten the production cycle and reduce energy consumption. Adding a small amount of nucleating agent can significantly improve its transparency. It can be widely used in the production of high-speed molded thin-wall (food) containers, high-speed injection recording (sound) Boxes, CD cases, etc., currently have an annual demand of more than 200,000 tons in the domestic market.
