On September 18th, one of Sinopec's 'Shizhilong' research project, high-gloss impact polypropylene, was successfully trial-produced in Zhenhai Refinery.
High-gloss impact polypropylene is mainly used in the field of injection molding. It can be used as a raw material for washing machine, microwave oven and other home appliance parts and automotive interior parts, toys, etc. It is characterized by excellent gloss index and can greatly improve the aesthetics of the product. Zhenhai Refining and Chemical Co., Ltd. cooperates closely with Beihua Institute. Through in-depth study of the microstructure and properties of polypropylene products, it overcomes the key technical problems of improving the gloss of impact polypropylene. Hydrogen production is used to produce high-gloss polypropylene. Compared with the conventional grades, the viscosity is relatively high, and it is prone to block the pipeline. During the production process, the operator carefully controls the temperature of the pipeline every hour to ensure that the new grade production process is stable and controllable.
