Poly(ethene) can either be a high-density or a low-density polymer, and each has a different structure. These differences depend on what monomers they are made from and the conditions in which they are made. These conditions could include the temperature at which the polymer is made, for example.
Low density poly(ethene) (LDPE)
High density poly(ethene) (HDPE)
Plastics can also be thermosetting or thermosoftening, and this is again due to the conditions in which they are made. The thermosetting or thermosoftening status of the plastic determines whether it can be recycled or not.
