Description
Comprehensive Overview of HDPE 52518 Injection Moulding Grade
Manafacturer: Jam Petrochemical Co
HDPE 52518 is a high-density polyethylene copolymer specifically developed for injection moulding applications that demand an excellent balance between processing ease, high flowability, and reliable mechanical performance. Produced using advanced Spherilene gas-phase technology, this grade offers consistent quality and stable processing behavior across a wide range of moulding conditions.
Key Material Characteristics
HDPE 52518 features a density range of 0.950 to 0.954 g/cm³ and a melt flow index of 16–20 g/10 min, making it particularly suitable for high-fluidity injection moulding processes. Its optimized molecular structure allows smooth melt flow, short cycle times, and precise mould filling, even in complex or thin-walled designs.

Processing Advantages
This grade is designed for easy processability and consistent performance in standard injection moulding equipment. Recommended barrel temperatures typically range between 190°C and 280°C, allowing flexibility across different machine settings. The high flow behavior supports efficient production, reduced energy consumption, and improved output rates.
Integrated additives such as thermal antioxidants and catalyst neutralizers enhance melt stability during processing and help protect the polymer from degradation, ensuring reliable performance during both manufacturing and end use.
Main Applications
HDPE 52518 is widely used in the production of:
- Housewares and household items
- Consumer plastic products
- Thin-walled injection-moulded parts
- Components requiring high flow and surface quality
Safety and Handling
When processing molten HDPE 52518, appropriate safety measures should be followed. Protective gloves and safety glasses are recommended to prevent thermal injury. Adequate ventilation should be ensured during melt processing. Accumulation of polymer dust or fines should be avoided due to potential explosion hazards, and proper grounding and filtration systems are advised.
Storage and Packaging
HDPE 52518 is supplied in pellet form, typically packaged in 25 kg bags, with alternative packaging options available upon request. For optimal material performance, storage should be in a cool, dry, and dark environment, away from direct sunlight and heat sources. Under proper storage conditions, the material maintains its original properties for up to 18 months, although processing within 6 months of delivery is recommended.
Conclusion
HDPE 52518 is a versatile and reliable injection moulding grade that combines high flowability, processing stability, and dependable mechanical properties. Its consistent performance and broad application range make it an excellent choice for manufacturers focused on efficiency, quality, and long-term durability.
