Polyether polyols are initiated with orthocyclohexanediamines such as 1,2-diaminocyclohexane. 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.

Polyether polyols are initiated with aminocyclohexanealkylamines such as isophoronediamine and 1,8-diaminop-menthane. 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.

Amine-initiated polyols and rigid polyurethane foam made therefrom

Rigid polyurethane foams are made using a polyol component that includes toluene diamine-initiated polyols containing specified levels of oxyethylene groups. Foams made from these polyols have low k-factors and excellent demold expansion values.
