Product Quality and Performance

• Strength and Rigidity: Sinopec’s polypropylene resins generally offer good strength and rigidity, comparable to many leading brands. This allows for the production of durable products such as plastic containers, automotive parts, and industrial components. However, some high-performance grades of competitors like LyondellBasell might have slightly superior strength properties in certain applications, but Sinopec also has a wide range of grades to meet different strength requirements2.
• Impact Resistance: In terms of impact resistance, Sinopec’s copolymer grades provide decent performance. They can be used in applications where moderate impact resistance is needed, like some household appliances and automotive interior parts. Nevertheless, some competitors may have developed specialized impact-modified polypropylene grades with enhanced toughness for more demanding applications, such as in the manufacturing of heavy-duty industrial equipment or outdoor sports gear23.
• Heat Resistance: Sinopec’s resins typically have a melting point in the range of 164℃ to 170℃, enabling them to withstand relatively high temperatures without significant deformation. This is on par with the heat resistance of many other leading brands and makes them suitable for applications such as food packaging that may require sterilization processes or automotive components exposed to engine heat23.
• Chemical Resistance: The chemical resistance of Sinopec’s polypropylene resins is excellent, similar to that of other major brands. They are resistant to acids, bases, and many common solvents, which is crucial for applications in the chemical industry, such as storage tanks, pipes, and chemical-resistant linings23.

Product Range and Customization

• Product Diversity: Sinopec offers a wide variety of polypropylene resin grades, including homopolymers, random copolymers, and block copolymers, to cater to different application needs. This product range is comparable to that of other leading manufacturers, providing customers with options for various end uses, such as injection molding, extrusion, and blow molding23.
• Customization Capability: Sinopec has the ability to customize polypropylene resins according to specific customer requirements. It can modify the resin’s molecular weight, melt flow rate, and other properties to meet the unique needs of different industries and applications. Similarly, other leading brands also offer customization services, but Sinopec’s extensive R&D and production capabilities enable it to provide competitive customization solutions123.
