SK R370Y is a high fluidity homopolymer polypropylene (PP) from SK Korea, primarily for thin-wall injection molding. Its key properties include high melt flow rate (50 g/10min), excellent rigidity, and good processability, ensuring fast production cycles and precise replication. It's widely used for food containers, housewares, and disposable items. Processing requires adequate injection pressure and speed to fill thin walls; controlled mold temperature (20-60°C) is crucial to prevent warpage or sinks. Proper drying (80-90°C for 1-2 hours) is recommended to avoid potential defects.

TotalEnergies HJ730 is a high-impact copolymer polypropylene (PP) from Korea. It offers excellent impact resistance, especially at low temperatures, and good stiffness. This balance makes it ideal for automotive parts like bumpers, household appliances, and industrial containers. For processing, ensure thorough drying before molding. Use appropriate injection speeds and pressures to manage the material's viscosity and prevent weld lines. Maintaining correct mold temperature is key to achieving optimal surface finish and mechanical properties.

GLOBALENE® PP ST868M is a high-crystallinity, high-rigidity homopolymer polypropylene. It features a high melt flow rate (approx. 45 g/10min) for excellent processability, along with good stiffness and heat resistance. Its primary application is in thin-wall injection molding, making it ideal for producing food containers, housewares, and disposable items requiring fast cycle times. For processing, pre-drying is recommended. Optimal results are achieved by using high injection speeds and pressures to fill thin-walled molds efficiently, while controlling mold temperature is crucial to minimize warpage and achieve a superior surface finish.
