THERMOPLASTIC POLYURETHANE FOR SEAL APPLICATIONS |
| 摘要 |
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. |

1. A thermoplastic polyurethane, obtained by a process comprising reacting reagents comprising
(a) a isocyanate with a (b) a polyol component comprising a polyester diol (b1), a polyether diol (b2) and a polycarbonate diol (b3), each having a molecular weight in a range of from 500 to 5000 g/mol, and (c) a diol having a molecular weight of from 62 g/mol to 500 g/mol. |
