ABSTRACT:
The incorporation of formic acid modified low equivalent weight amino polyols as crosslinkers in molded polyether polyurethane semiflexible foams is disclosed. These formic acid modified amino polyols result in foams which, when molded, display improved flowability, lower molded density and decreased usage per part. These improvements are demonstrable over nonformic acid modified low equivalent weight amino polyols and other commercial crosslinkers. The resulting foams find use in energy absorbing applications in the automotive industry and other industries.
