A method for the production of polyurethane elastomers with a high heat state behavior

摘要

The invention relates to a method for producing polyurethane elastomers, especially based on the fact that the polyether polyols or polyester polyols used have an initial function of at least 2 and the polyether polyols or polyester polyols used in the production of the NCO prepolymers used have an initial function of at least 4. The inventive method is characterised in that the polyurethane elastomers exhibit improved processing behaviour, combined with an increased heat resistance of the polyurethane materials produced therefrom.
