DuBay Polymer in Hamm-Uentrop is a chemicals company with ultra-modern production facilities, which it is clear to see, are just a few years old. In fact, this joint venture between LANXESS and DuPont – both are 50 percent stakeholders – was only established in 2001.

Since then polymers have been produced at this site from polybutylene terephtalate (PBT). LANXESS refer to these technical plastic as Pocan®, whereas DuPont call is Crastin®. They are used, for example, in the field of green mobility, in the electrical and electronics industry, in mechanical engineering, the chemicals industry and  in apparatus engineering.
