Energy absorbing flexible foams produced in part with a double metal cyanide catalyzed polyol

摘要

Energy absorbing flexible foam is prepared by reacting organic polyisocyanate with polyol blend having first and second polyol, blowing agent, and catalyst(s). The first polyol is prepared in part through active double metal cyanide catalyst. The second polyol is prepared in part through a basic or acidic catalyst. The average functionality of the first polyol is >=1.9, and the second polyol is 1-6. An independent claim is also included for an energy absorbing flexible foam comprising the reaction product organic polyisocyanate; and polyol blend having first and second polyols, blowing agent, and catalyst(s).
