Its role Owner
DuBay Polymer GmbH (DuBay) is a German polymer producer based in Hamm‑Uentrop, North Rhine‑Westphalia. The company specializes in manufacturing polybutylene terephthalate (PBT) base polymer, which is supplied to engineering plastics compounders in Europe and beyond.
Established as a joint venture originally formed by DuPont and Bayer (with ownership subsequently held by their successor companies), DuBay operates dedicated PBT polymerization units serving applications in automotive, electrical and electronics, and industrial sectors where rigidity, heat resistance, and dimensional stability are required. The company’s role is focused on upstream PBT production rather than compounding, providing consistent feedstock for downstream processors and brand owners.
