Selenis has acquired the production assets of Polisan Hellas in Greece and will operate more than 200,000 metric tonnes of annual installed specialty copolyester capacity by 2028, across plants in Portugal, Italy, Tunisia and the United States.

The company announced the deal on October 8, 2026. It describes itself as the only specialty copolyester producer manufacturing in Europe. The Polisan Hellas assets will be installed in Portugal, in line with a capacity doubling already announced and underway.

What does the acquisition change technically?

The purchase adds continuous polymerisation to a manufacturing base built on batch flexibility. Continuous production serves high-volume markets where standardisation, consistency and cost per tonne matter. Batch production handles specialty and custom grades, where smaller volumes, fast changeovers and formulation depth drive the economics.

With both technologies across four countries, Selenis can serve the full spectrum — from high-volume applications to specialised grades.

"We believe Europe needs a strong specialty materials manufacturing base, and we are investing to build it," CEO Duarte Matos Gil said. "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."

What does it mean for converters' supply risk?

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. That removes dependency on a single line or region and allows volume to shift between sites as demand and logistics change. Qualification will follow the technical and approval requirements of each application.

The company says European converters will be supplied from Europe and American converters from the United States, with shorter lead times and lower safety stocks than imported resin requires. These are announced intentions; measured lead-time gains will only show once the Portuguese installation ramps up.

Where does the cost advantage sit?

Continuous polymerisation runs at a lower conversion cost per tonne than batch. Selenis will direct standard grades for shrink sleeves, film and sheet onto that line, and says the competitiveness supports multi-year, qualified supply agreements with customers who commit predictable volume on both sides.

The investment targets four priority markets:

• Shrink sleeves, film and sheet — uniform high-volume grades at a competitive cost base, backed by the packaging know-how of the wider IMG Group.
• Healthcare — the Selcare® range, where multi-site qualification and continuity of supply are conditions of doing business.
• 3D printing — Mimesis™ PETG and PCTG resin for filament producers serving industrial manufacturing, automotive, electronics, education and consumer applications.
• Textile-to-textile recycling — Texnascis™ works with chemical recycling partners to turn recovered monomers into new polyester, with Selenis supplying the polymerisation expertise and industrial scale.

What comes next?

The Group is already assessing further investments. Eduardo Santos, Strategy & Integration Director at IMG Group, said: "We are evaluating new investments in Germany in the bio-based field and in Tunisia, where we are exploring textile-to-textile opportunities through DMT technology."

Santos added that each investment adds a capability to one manufacturing platform and is chosen for the markets where customers see the strongest long-term growth. Matos Gil signalled that further steps will follow the Polisan Hellas deal.
