摘要： 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.

摘要： Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are formed into an emulsion that includes a polyether containing oxyethylene groups, a nonionic surfactant and certain fumed silica, carbon black or talc particles.

摘要： Recovery time 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 10,000 centipoise at 25° C., having a glass transition temperature of at most 15° C. and being inert to other components of the foam formulation.
