| titleOfInvention | Microcellular polyurethane elastomers |
| abstract | The invention is directed to a method for producing a shaped body comprising a polyurethane elastomer, comprising the steps of (i) providing a mixture (M1), comprising at least one prepolymer having isocyanate groups, wherein the prepolymer is obtained by reacting a polyol composition (ZP) and an isocyanate composition (ZI) comprising at least 1, 5-naphthalene diisocyanate (NDI) and 4.4' - diphenylmethane diisocyanate (MDI), at least one chain extender (KV); (ii) introducing of the mixture (M1) into a mold; (iii) heating the mixture (M1) in the mold to a temperature in the range of 140°C to 200°C to obtain one shaped body (F1); (iv) deforming the molded article (F1) to obtain a molded body precursor (V2); (v) treating the shaped body precursor (V2) at a temperature ranging from 170 °C to 235°C to obtain a molding (F2) comprising a polyurethane elastomer. |
