Polyethylene is a polymer made from the polymerization of ethylene monomers. It is extensively used in packaging, containers, pipes, and numerous household goods. The polymerization process can be tailored to produce different types of polyethylene, such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE), each having distinct properties and applications.
