  • Patent number: 11312809
    Abstract: Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 5,000 centipoise at 25 #C and having a glass transition temperature of at most 20 #C. The tackifier is pre-blended with certain monols to form a lower-viscosity blend that is combined with one or more other polyols and a polyisocyanate to form a reaction mixture for producing a polyurethane foam.

  • Publication number: 20210301069
    Abstract: Flexible polyurethane foams having high airflows and excellent viscoelastic properties are made using a polyol mixture that includes a certain liquid polyester, certain ethylene oxide polyols and certain propylene oxide polyols, and a polymeric MDI. When used in applications such as bedding, the high airflows contribute to an improved sense of comfort by the user.
