Product type
HDPE Blow Molding Grade is a type of high-density polyethylene specifically formulated for blow molding applications. It is known for its excellent strength-to-density ratio, making it a popular choice for producing lightweight yet durable products. This grade of polyethylene is typically characterized by its high molecular weight and low melt flow index, which contribute to its processing capabilities and end-use performance.
| Density | 0.93 to 0.97 g/cm³ |
| Melt Flow Index | 0.1 to 20 g/10 min |
| Tensile Strength | 20 to 30 MPa |
| Elongation at Break | 300% to 800% |
| Processing Temperature | 180 to 220 °C |
When selecting HDPE Blow Molding Grade, buyers should consider the specific application requirements, including the desired mechanical properties such as tensile strength and elongation. It is also important to specify the melt flow index to ensure compatibility with the blow molding process. Certifications and compliance with industry standards may be relevant, depending on the end use. Quantities should be discussed based on production needs, as larger orders may offer cost benefits.
