Polyol mixtures containing 1,3- and / or 1,4-bis (aminomethyl) cyclohexane-initiated polyols and at least one of methylene bis (cyclohexylamine) -initiated polyols and cyclohexanediamine-initiated polyols, and made therefrom Polyurethane

摘要

Polyether polyols are initiated 1,3- and/or 1,4-bis(aminomethyl)cyclohexane) and with either or both of a methylene bis(cyclohexylamine) compound and a cyclohexanediamine compound. The polyols are useful in making rigid polyurethane foams, especially foams for pour-in-place applications, where they give a good combination of low k-factor and short demold times.
