en.Wedoany.com Reported - On March 24, Sinopec Sichuan Petrochemical Company completed the trial production of over 1500 tons of the high-melt-flow impact-resistant product CI93M at its 450,000-ton-per-year polypropylene plant. Inspection results showed that all performance indicators of this batch met industry premium standards. This successful trial production marks a technological breakthrough for Sichuan Petrochemical in the field of high-end polyolefin new materials, providing new momentum for the company to advance towards the mid-to-high end of the "refining-chemicals-precision-materials" industrial chain.
CI93M belongs to the high-end material family of polyolefins, possessing excellent rigidity-toughness balance and processing fluidity. It is primarily used in automotive components, home appliance housings, and high-end injection molding fields. This product has high technical barriers, with extremely stringent requirements on the catalyst system, ethylene distribution control, and extruder stability during production. It also faces challenges such as significant process parameter fluctuations and reactor caking. To ensure a successful first-time startup, the company formed a joint task force comprising the Production Operations Department, Planning and Technology Information Department, Chemical Division II, and the Quality Inspection Center.
Through repeated scheme comparisons, multiple rounds of desktop simulations, and practical operation simulations targeting key parameters like reactor temperature and pressure, the task force scientifically optimized the process indicators. During the trial production period, technical personnel strengthened refined control throughout the entire process, strictly adhered to safety regulations, and effectively addressed the challenge of transition material control by increasing sampling frequency, optimizing the PDS discharge system, and granulator operation. This ensured smooth powder conveying and qualified pellet indicators. Ultimately, the plant achieved the expected goals of "low consumption, high efficiency, superior indicators, and no pollution," precisely meeting the needs of downstream high-end customers.
Sichuan Petrochemical will closely monitor customer feedback on CI93M trials and continuously optimize product performance. The successful application at the 450,000-ton-per-year polypropylene plant not only consolidates the company's position in the high-end polyolefin market but also, driven by technological innovation, promotes high-quality development and helps break foreign technological monopolies. With the release of high-end polyolefin production capacity, Sichuan Petrochemical's technological accumulation in polypropylene plants will further translate into market advantages.
