Biesterfeld Group has announced the appointment of Jonas Borgsten as Global Business Director for the Engineered Polymers business unit. The change will take effect on March 1, 2026 and covers responsibility for the global development of activities in the field of engineered polymers. Jonas Borgsten, who joined Biesterfeld in 2024, will succeed Martin Rathke, who is leaving the company after more than 18 years.
The new Global Business Director holds degrees in business administration (MBA) and polymer science. He combines a business background with technical knowledge of the plastics market, which is relevant for the further development of the global Engineered Polymers unit. The decision to change the head of the business unit is part of the implementation of the Biesterfeld Group's strategy, in which the engineered polymers segment has been defined as one of the key growth areas.
In his professional career to date, Jonas Borgsten has gained experience in international chemical and plastics companies, including Dow Chemical and DuPont.

By taking on the new function, Jonas Borgsten will combine his existing regional responsibilities with the role of global director of the Engineered Polymers business unit. This means an extended scope of tasks that includes shaping the global business strategy of this unit, supervising its development in individual markets and further strengthening Biesterfeld Group's position in the field of engineered polymers.
