The present disclosure relates to a method of making polyurethane foam, the method comprising providing a polyol mixture comprising polyether polyol and unmodified vegetable oil having a hydroxyl number of less than 10; and reacting isocyanate with the polyol mixture to form a polyurethane foam, wherein the unmodified vegetable oil does not react and does not form part of the polyurethane foam. The present disclosure also relates to polyurethane formed by the method and polyurethane compositions.

A steering wheel includes a core and a foamed polyurethane coating that covers a ring section of the core. The foamed polyurethane coating is formed by foam molding of a polyurethane material containing 91 parts by mass of a base polyol, 10 to 25 parts by mass of a pigment, 1 to 3 parts by mass of a benzotriazole ultraviolet absorber, 0.8 to 2.5 parts by mass of a hindered amine photostabilizer, and a polyisocyanate. A total amount of the ultraviolet absorber and the photostabilizer is 2.7 parts by mass or more. The foamed polyurethane coating is in the form of an integral skin foam including a highly foamed core foam and a lowly foamed skin layer. The surface of the skin layer is not provided with a coating film formed from a coating material, and serves as a product surface that assumes a color of the pigment.

There is provided a curable resin composition capable of obtaining a resin molded body that is excellent in wear resistance and has a high flexural modulus. The curable resin composition according to the present invention contains a polyol compound, an isocyanate compound, a long reinforcing fiber, and a filler, in which the specific gravity of the filler is less than 4 and the average circularity of the filler is 0.65 or more.

The present invention relates to a process for producing flame-retarded polyurethane foams, in particular flexible polyurethane foams, using halogen-free flame retardants, wherein the resulting flame-retarded polyurethane foams exhibit low emission values coupled with good mechanical properties. The present invention further relates to halogen-free flame retardants.

This invention relates to improved flexible foams prepared from polymer polyols and to a process for preparing these improved flexible foams.

Golf ball multi-layered core sub-assemblies and the resulting golf balls are provided. The core structure includes a foam inner core (center); and intermediate and outer core layers. Foamed polyurethane is preferably used to make the inner core. The intermediate and outer core layers are preferably made from non-foamed thermoplastic compositions such as ethylene acid copolymer ionomer. In an alternative version, the intermediate core layer may be made of a thermoset rubber such as polybutadiene. The core layers have different hardness and specific gravity levels. The core structure and resulting ball have relatively good resiliency.

The present invention discloses a viscoelastic sound-absorbing polyurethane foam and a method for preparing the same, the foam being prepared by reacting a polyisocyanate composition and an isocyanate reactive component. The isocyanate reactive component comprises, based on the weight of mixed polyethers, 30-80 wt % of (bii) a copolyol of epoxypropane-epoxyethane, or a conjugate thereof, wherein the content of oxy-ethylidene unit is 5-35 wt %; 2-20 wt % of (biii) a copolyol of epoxypropane-epoxyethane, or a conjugate thereof, wherein the content of oxy-ethylidene unit is 70-100 wt %; and 20-70 wt % of (biv) a copolyol of epoxypropane-epoxyethane, or a conjugate thereof, wherein the content of oxy-ethylidene unit is 0-20 wt %. The sound-absorbing foam of the present invention has a ball rebound rate of 15-30% and good sound absorption performance.

A method for deblocking a blocked isocyanate is described herein. The method includes contacting a blocked isocyanate and a halide ion source under conditions effective to provide a deblocked isocyanate. A method of making a polyurethane is also disclosed. The method of making a polyurethane includes combining a blocked isocyanate, a polyol, and a halide ion source in the presence of solvent and under conditions effective to provide the polyurethane.

A method of forming a flame resistant flexible polyurethane foam that has a V-0 rating, according to Underwriters Laboratories Standard 94 Flammability Test, includes forming a reaction mixture that has an isocyanate component and an isocyanate-reactive component, and the isocyanate-reactive component includes a polyol component. The isocyanate component includes at least 30 wt % of a biuret modified aromatic diisocyanate, based on a total weight of the isocyanate component, and an isocyanate index of the reaction mixture is less than 100. The polyol component includes at least 5 wt % of a filled polyether polyol and at least 65 wt % of one or more other polyols that are different from the filled polyether polyol, based on a total weight of the isocyanate-reactive component.

Disclosed are a polyurethane composition, a molded article, and a vehicle comprising the polyurethane composition or the molded article. The polyurethane composition comprises a polyol composition (A) in which polyether polyol (a1) and polymer polyol (a2) are mixed at a predetermined amount, an isocyanate composition (B) obtainable by polymerizing polyether polyol (b2) and an isocyanate composition (b1) that comprises i) methylene diphenyl isocyanate (M-MDI) and ii) polymethylene diphenyl isocyanate (P-MDI). As such, the molded article such as a vehicle seat pad can be manufactured with improved static and dynamic comfort.
