Abstract
The incorporation of a crosslinker comprising an ethylene oxide adduct of a Mannich condensate of nonyl phenol, diethanolamine and formaldehyde in molded polyurethane semiflexible foams is disclosed. Semiflexible polyurethane foams incorporating this crosslinker result in foams which offer many advantages including a significant improvement in moldability characteristics and materials utilization as well as other advantages. These improvements are demonstrable over similar formulations using other crosslinkers. The resulting foams find use in energy absorbing applications in the automotive industry and other industries.
