| 摘要 |
The invention relates to a method for producing polyurethane-coated line elements, in which (a) aliphatic polyisocyanate is mixed with (b) compounds containing at least two isocyanate-reactive hydrogen atoms, (c) catalyst, and (d) optionally, other auxiliary agents and/or additives, to obtain a first reaction mixture, and said reaction mixture is directly or indirectly applied to a tube and is allowed to finish reacting to obtain a polyurethane layer, wherein the compound containing at least two isocyanate-reactive hydrogen atoms contains a compound that is based on an alkoxylation product of an aromatic starter molecule. The invention further relates to line elements obtainable according to a method of this kind. |
