 High-density polyethylene

High-density polyethylene (HDPE) is a type of thermoplastic polymer made from the monomer ethylene. It is known for its high strength-to-density ratio, making it one of the most widely used plastic materials in various applications. Here are some key characteristics and properties of HDPE: 1. **Density**: HDPE has a higher density (typically around 0.93 to 0.
