One-shot polyurethane elastomers with very low compression sets |
摘要 |
<p>This invention relates to a process for the production of polyurethane elastomers having low compression sets. The process comprises reacting A) an isocyanate component comprising methylene bis(phenyl isocyanate) containing the 2,4'-isomer of methylene bis(phenyl isocyanate), with B) an isocyanate-reactive component, optionally, in the presence of C) one or more additives. The reaction components are processed via the one-shot process at an isocyanate index of 90 to 130.</p> |
