Custom Polyurethane

Since decades, the group of Fietz companies has dealt with extensive sealing technology problems. We therefore represent expertise in the areas application technology, materials, and manufacturing techniques.

Within the global sealing industry, polyurethanes have turned into a dominant class of materials in the last decade. Their features are now seen as an important prerequisite when it comes to enabling for instance innovative components or systems with a longer service life and reliable functionality. Upon founding a development department and as a result of custom products of a high performance FiPur polyurethane portfolio, we have taken up this trend consistently.
