Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** China’s first batch production facility capable of producing 500,000 tons per year of new-generation bottle-grade resin chips has been put into operation at Yizheng Petrochemical. On January 17, 2025, China’s first facility of this kind, utilizing polyester medium-viscosity processing technology, was launched at Sinopec Yizheng Petrochemical Company. This project employs the most advanced short-process production technology developed by Sinopec, marking a new breakthrough in terms of technology and equipment in China’s polyester non-fiber industry. To date, all 3 projects of the first phase of Yizheng Chemical Fiber’s 850,000 tons per year production facility for functional polyester new materials have been completed and put into operation, contributing to the optimization of China’s polyester industry structure and providing material support for the advanced development of China’s manufacturing sector. 　　The first phase of Yizheng Chemical Fiber’s 850,000-ton-per-year production facility for functional polyester materials is one of Jiangsu Province’s key projects for 2023. This first phase includes the already operational plant with an annual production capacity of 230,000 tons of intelligent short fibers, as well as a project for the flexible transformation of production facilities with an annual capacity of 120,000 tons of PBT and 60,000 tons of PBxT. Additionally, there is the newly commissioned facility with an annual capacity of 500,000 tons for producing next-generation bottle-grade polyester materials. Together, these facilities enable the production of 850,000 tons of functional polyester materials per year, thereby generating economic value worth billions in the related industries and helping to meet people’s new needs in terms of clothing, food, housing, transportation, as well as health and environmental protection. 　　Innovation drives progress to meet the new demands for a better life. Polyester bottle chips are a plastic material made from polyester, featuring advantages such as light weight and recyclability. They are widely used in areas like beverage packaging and sheet materials, and are closely related to people’s daily lives. Our country is the world’s largest producer, consumer, and exporter of bottle blanks, but there is still room for development in certain high-end areas where special performance requirements apply. Yizheng Chemical Fiber’s 500,000 tons per year bottle preform production project is capable of manufacturing carbonated beverage bottles, hot-fill beverage bottles, plastic-steel strips and sheets, as well as various new specialty polyester products. It utilizes the most advanced short-process production technology developed by Sinopec, resulting in higher product quality; the crystallinity is lower compared to traditional processes, which makes the products more suitable for use by downstream users in areas such as blow molding. 　　“Move toward sustainability to build new competitiveness. The traditional polyester bottle grade chip production process requires first producing low-viscosity base chips, which are then modified to increase their viscosity to produce polyester chips suitable for use in bottles. Yizheng Chemical Fibers’ 500,000 tons per year bottle-grade polyester chip project breaks away from traditional production processes; it achieves a \"leapfrogging\" connection from raw materials straight to bottle-grade polyester chips. This approach makes the production process more energy-efficient, with an expected reduction of carbon emissions by over 20%. The indicators related to energy consumption and material usage are at the leading level in China. Furthermore, the localization rate of the equipment for this project reaches 95%, and it is located adjacent to the upstream facilities, enabling better integrated coordinated development. 　　Yizheng Chemical Fiber is a benchmark enterprise in China’s polyester and fiber industry. In recent years, the company has maintained a leading position globally in terms of the production and sales volume of polyester staple fibers. In the domestic high-end market for spunbond non-woven fabrics, its share exceeds 70%, making it the top brand in this sector. Since 2018, it has continued to be recognized as an \"Outstanding Supplier in China’s Non-Woven Fabric Industry\". In addition, the film-grade slices produced by the company have been recognized as National Manufacturing Single-Champion Products. It is the first enterprise in China to obtain certifications from both Coca-Cola and PepsiCo, and it boasts a laboratory for injection molding and blow molding that is among the best in the country. On October 14, 2024, the Zhengzhou Commodity Exchange designated Yizheng Chemical Fiber bottle chips as approved bottle chip delivery brands and brands exempt from inspection.
