Recently, the polypropylene unit of Chemical Division III successfully developed a new high melt flow index injection molding grade product, PPH-MN90, marking another significant addition to the company's portfolio of high-end polypropylene materials. PPH-MN90 is the company's first high melt flow index injection molding grade polypropylene product, boasting excellent processing performance and food safety, and can be widely used in food packaging such as fresh food containers and fast food containers.
High Melt Flowability: High melt flow index results in higher injection molding efficiency, suitable for the rapid production of thin-walled food containers.
Excellent Mechanical Properties: Combining rigidity and toughness, ensuring the stability of packaging containers during transportation and use.
Food-Grade Safety: Meets national food contact material standards, safe for use in packaging fresh food, fast food, and other direct contact food products.
Environmentally Friendly: The product is recyclable, helping downstream customers respond to the "plastic reduction" and sustainable development needs.
For this development, Fujian Gulei Petrochemical Company Limited established a cross-departmental task force, led by the Production Operations Department, in collaboration with the Technical Planning Department, Business Department, and other departments. A comprehensive collaborative mechanism was established for scientific production scheduling, process optimization, and resource support, laying a solid foundation for the unit's successful conversion to produce this product. Due to the characteristics of high melt index products, the conversion of the unit to other production lines was extremely challenging, requiring high standards for stable catalyst injection, smooth adjustment of process parameters, and strict product quality control. Therefore, the Chemical Engineering Department III organized technical personnel to discuss and develop a comprehensive conversion plan. For the unit's high-load production conditions, process parameters were pre-calibrated to ensure stable reactor operation during catalyst injection. Simultaneously, operators were assigned to 72-hour shifts to monitor the reactor, precisely controlling temperature fluctuations and minimizing the generation of transition feedstock. The testing center closely cooperated with the conversion, conducting comprehensive quality testing throughout the process and providing timely feedback on key product indicators to support product adjustments and optimizations. Ultimately, through the joint efforts of all departments, the unit conversion was successful on the first attempt, with product performance meeting relevant standards and setting a new company record for reducing transition feedstock during polypropylene conversion.
This year, the company has vigorously promoted quality and efficiency improvement, encouraging all units to actively develop differentiated, high-value-added products based on market demand. The successful development of PPH-MN90 not only fills a product gap in this field for the company but also accumulates valuable experience for the development and application of high-end products. Jia Huaibin, manager of the Chemical Engineering Department III, said that the department will adhere to innovation-driven development and continue to develop high-performance, environmentally friendly, and differentiated products to gain market benefits with strong product competitiveness and effectively promote the high-quality development of the enterprise.
