Sinopec Yangzi Petrochemical, located in the Jiangbei New Area of Nanjing, Jiangsu Province, is one of Sinopec's core integrated refining and petrochemical production bases. Polyolefin manufacturing represents one of the company's primary business segments, with polypropylene (PP) serving as a key product line. Supported by advanced production facilities, a mature industrial chain, and large-scale manufacturing capabilities, the company has become one of China's leading suppliers of polypropylene resins.
Yangzi Petrochemical's polypropylene production unit officially commenced operation in 1987. The facility initially adopted advanced gas-phase polymerization technology from Mitsui Petrochemical of Japan and has since undergone multiple rounds of technological upgrades, capacity expansion, and process optimization. Today, it offers highly efficient large-scale production with the flexibility to manufacture a wide range of polypropylene grades while maintaining excellent operational stability.
Using high-purity propylene as the primary feedstock, together with ethylene comonomers and highly active catalysts, the production process carries out gas-phase polymerization under precisely controlled temperature and pressure conditions. The resulting polymer then undergoes drying, compounding, extrusion, pelletizing, screening, homogenization, and comprehensive quality inspection before being supplied as premium polypropylene resin pellets.
The entire manufacturing process is fully enclosed and highly automated, supported by comprehensive environmental protection systems, strict safety management, and rigorous quality control standards to ensure stable product performance that complies with both national and industry specifications.
Yangzi Petrochemical's polypropylene products feature low density, extremely low moisture absorption, excellent resistance to acids and alkalis, superior electrical insulation properties, and outstanding heat resistance. They are non-toxic, odorless, and easy to process using injection molding, extrusion, monofilament drawing, cast film extrusion, and other mainstream plastic processing technologies, making them suitable for a broad range of downstream industries.
Leveraging its mature polymerization technologies, reactor alloy technology, and advanced modification capabilities, Sinopec Yangzi Petrochemical has established a comprehensive polypropylene product portfolio covering four major categories:
These products serve applications across consumer goods, automotive manufacturing, construction, food-contact materials, medical devices, and advanced industrial manufacturing.

F401 is a premium raffia-grade polypropylene offering excellent drawability, stable toughness, and reliable processing performance. It is widely recognized as one of the major raw materials for China's packaging industry and is commonly used for manufacturing:
S700 is a high-flow homopolymer grade designed for high processing efficiency. It is suitable for:
Its excellent productivity makes it particularly suitable for large-scale manufacturing.
Impact copolymer polypropylene is one of Yangzi Petrochemical's signature product families. Major grades include J340, J440, K9015, and the YPJ series.
Manufactured using advanced reactor alloy technology, these products offer an excellent balance between rigidity and impact strength while maintaining outstanding low-temperature toughness, making them suitable for demanding operating environments.
K9015 is one of China's earliest domestically produced automotive polypropylene grades to receive Volkswagen Germany certification. It has long been supplied for manufacturing:
The YPJ series is widely used in manufacturing:
J340 offers excellent impact resistance and is commonly used for:
These grades have earned strong recognition throughout both domestic and international markets.
Sinopec Yangzi Petrochemical has established a comprehensive portfolio of polypropylene materials specifically developed for piping applications. Major grades include C180, YPR-R503, and PPH-EN00-S.
C180 is a random copolymer PP-R grade widely used for hot and cold water piping systems in residential and commercial buildings.
Its advantages include:
Yangzi Petrochemical has successfully achieved industrial-scale production of the high-end β-crystal polypropylene pipe material PPH-EN00-S, filling a major technological and production gap in China's premium industrial polypropylene pipe market.
The material provides:
Typical applications include:
The successful commercialization of this material has significantly reduced dependence on imported specialty polypropylene pipe materials.
The company's product portfolio also includes dedicated sheet grades and low melt flow industrial pipe materials, covering both residential and industrial processing requirements.
Food-contact and medical polypropylene products represent one of Yangzi Petrochemical's highest value-added product categories.
These materials emphasize:
All food-contact polypropylene grades comply with China's GB 4806 food-contact material safety standards.
Medical-grade products have passed ISO 10993 biocompatibility testing, while selected grades also comply with U.S. FDA and European CE requirements, meeting internationally recognized quality standards.
PPK1108 is a heat-resistant homopolymer polypropylene grade designed for food-contact applications.
Its excellent heat resistance and low extractable content make it suitable for manufacturing:
YPJ-1215C is a transparent medical-grade polypropylene capable of withstanding steam sterilization at 121°C.
Manufactured under cleanroom production standards, it features extremely low extractable substances and outstanding safety performance.
Typical applications include:
For many years, Sinopec Yangzi Petrochemical has remained committed to polypropylene technology development and continuous process innovation.
Supported by Sinopec's national research and development platform, the company focuses on the localization of high-performance specialty polypropylene materials while continuously improving product performance and expanding its portfolio of resin grades.
Through ongoing technological innovation and process optimization, Yangzi Petrochemical has significantly enhanced the stability, weather resistance, and application-specific performance of its polypropylene products, helping to reduce China's reliance on imported materials in key sectors including automotive plastics, medical materials, and industrial piping applications.
With stable production capacity, rigorous quality management, a comprehensive product portfolio, and industry-leading manufacturing technologies, Sinopec Yangzi Petrochemical has become one of China's benchmark polypropylene producers.
Its polypropylene products serve virtually every major domestic industry while being exported to numerous international markets.
By supplying reliable, high-quality polypropylene materials for consumer goods, automotive manufacturing, healthcare, renewable energy, infrastructure, and advanced industrial applications, Sinopec Yangzi Petrochemical continues to strengthen its position as a trusted global supplier and a key contributor to the sustainable development of the global polyolefin industry.
