HDPE Plastics – Key Technical Parameters and Practical Applications
HDPE Plastic (High-Density Polyethylene) is short for high-density polyethylene, a thermoplastic polymer belonging to the polyolefin family. Thanks to its low degree of molecular branching, HDPE has a high density (0.941–0.965 g/cm³), which gives it excellent mechanical strength, as well as high resistance to impact, chemicals, and moisture. HDPE Plastic has a hard, opaque white…
