Abstract
A polyurethane foam is prepared by combining a polyether triol with a hydroxyl value of from 25 to 30 and a molecular weight from 5000 to 7000 g/mol; a polyether diol with a hydroxyl value of from 25 to 30 and a molecular weight from 3000 to less than 5000 g/mol; a chain extender mixture including 1,4-butanediol and at least one of monoethylene glycol, hexanediol, neopentyl glycol, and isomers thereof; a copolymer polyether polyol having a styrene acrylonitrile solids content of at least 38 wt % and an average hydroxyl number of at least 23; an isocyanate component; and a blowing agent. It is particularly suitable for shoe sole applications, where it exhibits improvement in slip resistance under wet conditions when compared with some other polyether-polyurethane formulations.
