1.Quality Monitoring and Inspection

• In-Process Quality Monitoring: Continuous monitoring is carried out during the production process. Samples are taken at regular intervals for analysis of various properties such as MFR, isotactic index, and ash content. This allows for immediate detection of any quality fluctuations and timely adjustment of production parameters to maintain product quality stability.
• Finished Product Inspection: Comprehensive inspections are performed on the finished polypropylene resin products. Tests include physical property tests such as tensile strength, impact resistance, and heat resistance, as well as chemical property analyses. Only products that meet the strict quality standards are allowed to leave the factory.
• Quality Traceability System: Sinopec has established a quality traceability system that records detailed information about the production process, raw materials used, and inspection results for each batch of polypropylene resin. This enables quick identification and tracing of the source of any quality issues, facilitating effective corrective actions and preventing the recurrence of problems.

2.Research and Development and Technological Innovation

• Ongoing R & D Investment: Sinopec invests significant resources in research and development to continuously improve the quality and performance of its polypropylene resins. It focuses on developing new catalyst systems, polymerization processes, and product formulations to meet the evolving market demands for high-quality polypropylene resins with enhanced properties.
• Collaboration with Research Institutions: Sinopec collaborates with leading research institutions and universities to conduct in-depth research on polypropylene resin technology. By leveraging external R & D resources and expertise, it can accelerate the pace of technological innovation and improve its competitiveness in the polypropylene resin market.
• Customization to Meet Customer Requirements: Based on in-depth understanding of customer needs, Sinopec develops customized polypropylene resin products. It can adjust the product’s molecular structure, MFR, and other properties to precisely meet the specific requirements of different customers and applications, thereby enhancing customer satisfaction and loyalty.
