What is PE (as in HDPE, MDPE, LDPE, LLDPE, etc.) and what are some of its uses?
Polyethylene (PE) is a thermoplastic material belonging to a group of polymers called polyolefins. It is usually categorized by its density as indicated in the abbreviations; HDPE (high density PE), MDPE (medium density PE), LDPE (low density PE), and LLDPE (linear low density PE). Depending on its specific grade and properties, it is used in a wide range of plastic products from milk bottles and plastic bags to high performance plastic pipes.
