High-density polyethylene (PE-HD)
The material 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.
- Food-safe (unchanged taste and smell)

- Permanent temperature resistance from -40°C to 80°C (briefly up to 120°C)
- Low density of 0.94 g/cm³ (buoyant)
- Good UV and aging resistance
- Corrosion resistance
- Excellent electrical insulation properties
- Technical material, not optical plastic
