  • SEAL RING, SEALING ARRANGEMENT, AND USE OF A SEALING ARRANGEMENT
    Publication number: 20190285182
    Abstract: A seal ring in the form of a grooved ring for sealing a movable machine element toward a stationary housing includes: a radially inner axial leg with a dynamic sealing edge; a radially outer axial leg with a static sealing edge; and a radial leg connecting the two axial legs. The seal ring is produced from a thermoplastic material. A recess is formed between the two axial legs and the radial leg. The radially inner axial leg has, on a surface of the radially inner axial leg on a machine element side, a rounded transition to a surface of the radial leg that faces away from a pressure.

  • Thermoplastic polyurethane for seal applications
    Patent number: 10227443
    Abstract: 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.
