ABSTRACT:
Flexible polyurethane foams are prepared from polyols containing 0.1 to 5.0 percent by weight of an inorganic filler such as fumed silica having a pH value of 6-8.5 and an effective particle size of less than 7 microns. Foams molded from such polyols exhibit in some instances an improvement in some of the strength properties and do not alter substantially, the mold fill time. In addition, there is an improvement in foam porosity (air flow) as well as a reduction in the force required to crush foam articles.
