Selenis has acquired the production assets of Polisan Hellas in Greece for installation in Portugal. Including these assets, Selenis will operate more than 200,000 metric tonnes (MT) of annual installed specialty copolyester capacity by 2028, across production sites in Portugal, Italy, Tunisia and the United States.
The acquisition adds continuous polymerisation to a manufacturing base built on flexibility. Continuous production serves the high-volume markets, where standardisation, consistency and cost per tonne matter. Batch production serves specialty and custom grades, where smaller volumes, fast changeovers and formulation depth are key. With both technologies now part of its manufacturing platform across four countries, Selenis can serve the full spectrum of the market, from high-volume applications to specialised grades, combining the scale and efficiency of continuous production with the flexibility of batch manufacturing.
“We believe Europe needs a strong specialty materials manufacturing base, and we are investing to build it,” said Duarte Matos Gil, CEO of Selenis. “When customers qualify our materials, they make a long-term commitment. Our responsibility is to invest ahead of their needs, to put more than one plant behind every grade and to give them a cost base that lets them compete. This acquisition puts industrial capacity behind that commitment, and further steps will follow.”
Supply resilience is central to the expansion. Selenis will work with customers to qualify selected grades at more than one manufacturing site, so a converter can hold the same specification from two plants, with no dependency on a single line or region and with the flexibility to move volume between sites as demand and logistics change. Qualification will follow the technical and approval requirements of each application. European converters are supplied from Europe and American converters from the United States, with shorter lead times and lower safety stocks than imported resin requires.
