Product type
High Density Polyethylene (HDPE) granules are a type of thermoplastic made from petroleum. They are known for their high strength-to-density ratio, making them a popular choice in various industrial applications. HDPE granules are typically processed through extrusion or injection molding to create a wide range of products, from containers to piping systems.
| Density | 0.93 to 0.97 g/cm³ |
| Melt Flow Index | 0.1 to 20 g/10 min |
| Color | Natural or colored |
| Processing Temperature | 180 to 220 °C |
| Typical Applications | Containers, pipes, and automotive parts |
When selecting HDPE granules, buyers should consider the specific application requirements, such as density, melt flow index, and color. It is also important to specify the desired processing method, whether it be extrusion or injection molding. Buyers should inquire about certifications and compliance with industry standards, especially for applications involving food contact or medical use.
