LIQUID HARDNESS AGENT FOR OPEN CELL FOAMS

摘要

The present invention provides a ring-containing component polyol and process for making the same for use as a load-bearing capacity improvement agent in flexible polyurethane foam manufacture. The ring-containing component polyol eliminates and/or reduces the need for a copolymer polyol containing suspended solids in the manufacture of flexible foam products. This may reduce production costs, reactivity variations, filter plugging, color variations, foam shrinkage/tightness, foam irregularity, and foam malodor while maintaining an adequate load-bearing capacity. The present polyol blends can be non-opaque or transparent.
