Abstract:
A flexible, polyurethane foam suitable for applications where latex is used and having an Indentation Force Deflection (25% IFD) of about 3 lbs. formed by a process comprising reacting:a) 80 parts by weight of glycerine-based polyol having a molecular weight of about 6,000, a high primary hydroxyl content of about 75% and about 15% ethylene oxide cap; b) 20 parts by weight of a triol polyol containing 22.5% by weight of a styrene-acrylonitrile copolymer dispersed in the continuous phase of said polyol; c) 2 parts by weight of a glycerine-based polyol having a primary hydroxyl content of about 60% and about 70% ethylene oxide cap; d) 32 parts by weight of a polymeric MDI (diphenyl methane diisocyanate) having a functionality of about 2.2 and a NCO content of about 32 weight % and an isocyanate index of about 0.80; e) 2.2 parts by weight of water; f) 15 parts by weight of pentane; and g) an amine catalyst.
