Abstract
Provided are catalyst systems which produce flexible polyurethane polyester foams that are color stable, are lower in odor, and uses less catalysts than current most commonly practiced technology. The use of lower amounts of catalysts with low vapor pressure reduces worker exposure to alkaline corrosive materials, reduces pollution through less pounds of volatile organic chemicals (VOC's) and is less expensive.
