High-density polyethylene (PE-HD)

The plastic high-density-polyethylene (PE-HD) is a thermoplastic which, among other things, has the property of being reversibly deformable within a certain temperature range. The atomic structure is characterized by a concatenation of CH2 molecules, whereby the semi-crystalline structure enables the material to be welded. 

The global production volume of 40 million tons achieved in 2017 is the interim result of a decades-long continuous increase that stresses the material growing importance. In addition to container construction, PE-HD is also used for molded parts such as household goods, waste garbage cans and sewage pipes.
