Polyethylene (HDPE, MDPE, LDPE)

Polyethylene is one of the most diverse thermoplastic materials available. The density of polyethylene determines its physical properties: the higher the density, the stiffer the material. High density yields a higher softening point, with higher tensile and creep resistance. Unfortunately, the reverse effect is true and higher density properties result in a lower impact strength, elongation and flexibility. Common applications include: • Small tubing to large pipe, including natural gas, sewer pipe and drainage lines • Coatings for wire and cable • Large applications such as fuel tanks and containers Low density polyethylene (LDPE) is puncture and tear-resistant and is frequently used for films and bags due to its low crystallinity. It can also be found in coatings to help with heat sealability and moisture barriers.
