Freudenberg Sealing Technologies is introducing a new generation of polyurethane for seals that sets new standards. Freudenberg's development of its own materials is an important core competency. The company has succeeded in manufacturing a basic material for seals with a far longer operating life than the materials used so far. The new generation of polyurethane was developed for a wide array of uses. It offers superb performance in heat and cold, can be used in mineral hydraulic fluids at up to 120°C, and is safe from damage due to hydrolysis even when used in water heated to 80°C. But the material is also a genuine high performer when it comes to pressure. In a comparison test with various extrusion gaps, seals with the new generation of polyurethane show no appreciable sign of wear, while conventional seals malfunction prematurely. Its tensile strength also far surpasses current possibilities, measuring around 25 megapascals, or 35 percent above other materials.
