  • Agents for reducing the force-to-crush (FTC) of high support flexible foams
    Patent number: 6855742
    Abstract: The present invention provides a high support (HS) and high support-high resilience (HS-HR) flexible polyurethane foams prepared by catalyzed reaction of one or more di- or polyisocyanates at an isocyanate index from about 70 to about 130 with: (a) a polyoxyalkylene polyol or polyoxyalkylene polyol blend having an average hydroxyl weight of at least about 1000 and an average primary hydroxyl content of at least about 25%; and (b) an effective amount of a blowing agent containing water; in the presence of from about 0.01 to about 0.5% parts by weight based on 100 parts by weight of said polyol component of a liquid hydrocarbon containing greater than 50% of polymerized butadiene. The high support (HS) and high support-high resilience (HS-HR) flexible polyurethane foams of the present invention have a reduced force to crush (FTC).
