摘要

Polyol mixture for polyurethane foams comprises a polyester, two different polyols with ether bonds and an amino diol. Polyol mixture comprises: (a) a compound with at least one amino group and at least two hydroxy groups; (b) a compound with at least one ether bond and being free of amino groups and with 4-8C hydroxy groups; (c) a compound with at least one ether bond and being free of amino groups and with 3C hydroxy groups; and (d) a polyester with at least two hydroxy groups. Independent claims are included for a two-component agent for preparing polyurethane (PU) foams comprising the above polyol mixture and an isocyanate of average functionality at least two and also the obtained polyurethane foams.
