made quality

Zelu is the expert in polyurethane foam systems and adhesives. For more than 125 years our company has stood for chemical products of the highest quality.

For the 21st time, the Fachverband Schaumkunststoffe und Polyurethane e.V. (FSK – Specialist Association Foamed Plastics and Polyurethanes) presented its FSK Innovation Award, on 13 November in Reutlingen.

The award in the “Design and Structure” category went to DOLFINOS AG for a violin support made using a polyurethane foam developed in collaboration with ZELU CHEMIE GmbH. Thanks to this high-quality foam, DOLFINOS has succeeded in designing the first violin support that can be fully adapted to the needs of the musician.

Zelu tested a wide variety of polyurethane foam systems to find a product that met this specific requirement. As a result, the partners have been able to develop a long-lasting polyurethane cushion that does not lose its properties even after long periods of heavy strain.

We congratulate our client DOLFINOS on their success and look forward to working with them again in the future.
