High Density Polyethylene (HDPE) Balls
High-density polyethylene (HDPE) is a polyethylene thermoplastic derived from petroleum.
The mass density of high-density polyethylene typically ranges from 0.93 to 0.97 g/cm³. Although the density of HDPE is only slightly higher than that of low-density polyethylene, primarily due to little branching in the material, HDPE has a stronger intermolecular force and tensile strength than LDPE. The differential in strength exceeds the difference in density, giving HDPE a higher specific strength. HDPE is also harder, more opaque and can withstand higher temperatures of 120ºC/ 248ºF for short bursts and 110ºC/ 230ºF continuously.
Advantages of HDPE Balls
- Completely free from BPA – High-density polyethylene (HDPE) is, like BPA, a material derived from petroleum. The difference is that HDPE plastics are completely free from BPA and are therefore safe for applications that directly impact humans.
- Suitable for many industries – HDPE balls are suitable for a variety of industries, such as the food industry, which manufactures products explicitly for human consumption. They can be used for mixing, liquid flow control, and more.
