Product type
High-Density Polyethylene (HDPE) is a thermoplastic polymer made from petroleum. It is characterized by its high strength-to-density ratio, making it a popular choice in various industrial applications. HDPE is known for its durability, resistance to impact, and ability to withstand harsh environmental conditions, which makes it suitable for both indoor and outdoor use.
| Density | 0.93 to 0.97 g/cm³ |
| Melt Flow Index | 0.2 to 20 g/10 min |
| Tensile Strength | 20 to 37 MPa |
| Elongation at Break | 500 to 1000% |
| Temperature Resistance | -40°C to 60°C |
When selecting HDPE, consider the specific application requirements, such as density and melt flow index, which can affect processing and performance. Buyers should also specify the desired tensile strength and elongation properties based on the intended use. Additionally, inquire about any relevant certifications or grades that may be necessary for compliance in certain industries.
