ABSTRACT:
Flexible polyurethane foams having increased compression hardness are produced by reacting an organic polyisocyanate with a mixture of polyols in the presence of a blowing agent and optionally known additives such as catalysts, emulsifiers, etc. The mixture of polyols is (1) 75-95 wt % polyether polyol with terminal OH groups having a functionality of from 2 to 4 and an OH number of from 25 to 60 and (2) 5-25 wt % polyether polyol having a functionality of at least six and an OH number of from 150 to 200 which is the reaction product of an alcohol having a functionality of at least six and propylene oxide which has been modified to contain 5-50 wt % terminal ethylene oxide groups. These foams are useful in furniture applications.
