A thermoplastic polyurethane is obtained via reaction of isocyanates (a) with a polyol component (b) having at least one polyesterdiol (b1), at least one polyetherdiol (b2) and at least one polycarbonatediol (b3), in each case with a molar mass of from 500 to 5000 g/mol, and also with at least one diol with a molar mass of from 62 to 500 g/mol. The thermoplastic polyurethane can be used for producing moldings, more particularly seals, coupling stars, valves, and profiles. The polyurethane has exceptional mechanical and chemical properties.

Thermoplastic polyurethane for seal applications

A gasket includes a damping buffer for a piston that can be charged with a pressure medium and that can be moved back and forth axially in a cylinder pipe and includes at least one static seal for sealing the cylinder pipe vis-&#xe0;-vis a cover connected to the face of the cylinder pipe and a dynamic seal having at least one dynamically loaded sealing lip that, during the proper use of the gasket, can be laid against the surface to be sealed of a damping journal that is connected to and axially movable back and forth with the piston and that has at least one flow-guiding connection opening that connects the axial faces of the gasket.
