| description | Energy absorbing rigid polyurethane foams have both high energy absorbing efficiency as well as exceptional recovery after deformation, allowing their use in visible energy absorbing structures, particularly in the transportation vehicle industry. The foams are prepared by reaction of one or more di-or polyisocyanates with a polyol component containing both high and low molecular weight polyols, and optionally chain extenders, crosslinkers, and other additives, wherein at least one polyol is a polymer polyol such that the total vinyl polymer solids content of the foam is greater than 15 weight percent.< /SDOAB> |
