A unique, grafted polyether polyol containing copolymerized styrene and acrylonitrile, and filtered to 100 microns. It is used in the manufacture of flexible slabstock polyurethane foams, is manufactured without the use of BHT, and processes well on most types of foam machinery. This is designed for use in the full density range of high-loadbearing flexible foams used in carpet underlay and packaging. It can be used as the sole polyol, or may be blended with conventional polyether slabstock polyols to produce high-loadbearing foams over the density range of 1.2 – 4.5 lb/ft3.
