Polyplastics Expands Topas COC Production with New German Facility

Polyplastics, headquartered in Japan with a U.S. office in Farmington, Michigan, is constructing a new cyclic olefin copolymer (COC) plant in Leuna, Germany. The facility will be operated by the company’s German subsidiary, Topas Advanced Polymers GmbH, and is slated to start up in mid‑2023.

With an annual capacity of 40 million pounds (≈18 million kilograms), the new plant will more than double Polyplastics’ current German output. The existing Topas COC plant in Oberhausen – 245 miles west of Leuna – has been running since 2000 and has supported a wide array of applications, most notably in high‑purity medical devices that rely on the polymer’s glass‑like optical clarity and biocompatibility.

Topas COC has earned EU certification as a recyclable polyolefin, positioning it at the heart of the European Union’s circular‑economy strategy. In the packaging sector, the polymer’s superior barrier properties enable the creation of mono‑material structures that are easier to recycle than conventional multi‑layer PET/PE blends.

By expanding its COC production, Polyplastics is reinforcing its commitment to sustainability and innovation across both medical and packaging markets.
