High-Density Polyethylene (HDPE) is one of the most widely used polyolefin materials, valued for its excellent strength, wear resistance, chemical resistance, and processing versatility. It has become an essential raw material across industries such as manufacturing, consumer products, agriculture, infrastructure, and packaging.
As one of Sinopec's key integrated refining and petrochemical production bases, Sinopec Yangzi Petrochemical has been committed to the research, development, and production of HDPE for many years. Supported by advanced manufacturing technologies, rigorous quality control systems, and reliable production capacity, the company offers a comprehensive portfolio of high-performance HDPE grades that serve customers in both domestic and international markets, making it one of China's leading suppliers of premium HDPE resins.
Sinopec Yangzi Petrochemical produces HDPE resin in the form of smooth natural-colored cylindrical or flattened pellets with a uniform particle size ranging from approximately 2 mm to 5 mm. Powdered resin is supplied as pure white powder with extremely low impurity levels, providing an excellent foundation for downstream processing.
Compared with conventional polyethylene materials, Yangzi Petrochemical's HDPE offers a wide range of performance advantages suitable for diverse processing methods and application scenarios.
Its outstanding mechanical properties include high rigidity, excellent tensile strength, superior impact resistance, and excellent wear resistance. These characteristics make the resin ideal for extrusion, blow molding, injection molding, and monofilament drawing, enabling manufacturers to produce durable products with excellent dimensional stability.
The material also demonstrates excellent weatherability and outstanding low-temperature performance, maintaining reliable mechanical properties even under harsh environmental conditions, making it suitable for outdoor applications and cold-climate regions.
In addition, the resin provides excellent chemical stability with strong resistance to acids, alkalis, and various organic solvents. It also offers superior electrical insulation, moisture resistance, and impermeability while remaining non-toxic, odorless, environmentally friendly, and compliant with industrial and consumer safety requirements.
Excellent melt flow characteristics further improve processing efficiency, reduce scrap rates, and lower manufacturing costs for downstream processors, making the material highly suitable for large-scale industrial production.
To satisfy the diverse requirements of different industries, Sinopec Yangzi Petrochemical has developed multiple HDPE grades covering general-purpose, monofilament, film, and blow molding applications.
HDPE 5000S is one of Yangzi Petrochemical's flagship products. It features excellent drawability, high tensile strength, outstanding wear resistance, and excellent low-temperature performance, making it an industry-leading material for monofilament applications.
Typical applications include:
