From window seals and doors to industrial systems: seals ensure tightness, protection against environmental influences and energy efficiency. Despite their important function, they often go unnoticed.
This is exactly where Rubby comes in. The mascot of the poesia gruppe makes the world of seals, materials and applications easy to understand.
In chemically demanding applications, conventional elastomer O-rings quickly reach their limits, as they do not offer the required properties. With encapsulated O-rings made of PFA (perfluoroalkoxy pol-ymers) and FEP (fluorinated ethylene propylene), the poesia group provides solutions for demanding special applications.
Mit grosser Trauer nehmen wir Abschied von Hans Beat Christen, der am 8. April 2026 verstorben ist.
Hans Beat Christen war weit mehr als ein langjähriger Mitarbeiter – er war Mitgründer, Verwaltungsratsmitglied, Wegbereiter und eine prägende Persönlichkeit der heutigen poesia-gruppe. Als Mitgründer der pbc polymer ag hat er mit grosser Leidenschaft, unternehmerischem Weitblick und unermüdlichem Engagement den Grundstein für unseren heutigen Erfolg gelegt.
With the office expansion in Unterkulm, the poesia group is creating space for further growth and modern workplaces. Following the planned progress of the timber construction, the next key milestone is the installation of the new windows.
From 20–22 January 2026, the poesia group presented sealing solutions in TPE, silicone and LSR at Swiss Plastics Expo in Lucerne—featuring InflaSeal® as well as 3D-printed prototypes and small-batch production.
For many years, poesia-gruppe, based in Unterkulm, has been investing successfully in the future by training apprentices. It offers various apprenticeship programmes and thus provides young people with a promising entry into professional life.
Timo Steiner, first year commercial employee EFZ apprentice, found his first weeks of apprenticeship very pleasant. By now, he is very familiar with various tasks. He appreciates the good exchange within the team, which leads to joint solutions. Thanks to good organisation between work, school, studying and hobbies, he has found a healthy balance to manage everything successfully.
Swiss Plastics Expo will take place from 20 to 22 January 2026 at Messe Luzern. It is the trade fair and symposium for everyone working with plastics. The poesia-gruppe will present its sealing solutions at its own stand and will also appear as a manufacturer of high-quality sealing solutions.
The trade fair is aimed at experts from a wide range of plastic application fields: from industry and mechanical engineering to construction, gastronomy and medical technology. This unique industry event offers opportunities for inspiration, further education and networking.
Two successful days of innovation, interaction and high-performance sealing technology
The participation of the poesia group in maintenance Zurich 2025 was a major success. On 26 and 27 November, we presented our latest developments in industrial sealing technology, technical profiles manufactured in-house and customised solutions for demanding pump, valve and machinery applications.
High-performance sealing solutions, technical profiles and innovations in industrial sealing technology
From 26 to 27 November 2025, the poesia group will be exhibiting at maintenance Zurich – the leading Swiss trade fair for industrial maintenance, engineering and sealing technology. As a manufacturer and specialist for seals, O-rings, mechanical seals, TPE and silicone profiles and custom sealing solutions, we will present our expanded product range and innovations developed for demanding industrial environments.
The poesia group in Unterkulm is experiencing strong growth. To meet the increasing demand for space, the company began construction of an extension in July. The existing office building is being raised by three additional floors.
The poesia group is not just planning for the present but investing strategically in the future. Instead of adding only the space currently required, the company is doubling the expansion to ensure flexibility for future developments.
