The present disclosure relates to processes for the production of a polyurethane material, where (a) di- and/or polyisocyanates, (b) compounds which have hydrogen atoms reactive toward isocyanate groups and which do not include compounds having carbon-carbon double bonds, (c) compounds including at least one carbon-carbon double bond, (d) optionally catalyst that accelerates the urethane reaction, and (e) optionally other auxiliaries and additives are mixed to give a reaction mixture and the mixture is hardened at temperatures above 120 C. The present disclosure further relates to a polyurethane material obtainable by this process, and also to the use of the polyurethane material, in particular of a polyurethane fiber-composite material as structural components.

A method for producing a flexible-packaging film in which a first substrate and a second substrate are laminated with a reactive adhesive of a polyisocyanate composition (X) and a polyol composition (Y) therebetween includes a two-component separate application step in which a liquid mixture applied to the first substrate and including the polyisocyanate composition (X) and the polyol composition (Y), and a catalyst (Z) formed in a dot pattern on the second substrate are brought into contact with each other to achieve contact-bonding together. The substrates are preferably plastic films, metal vapor-deposition films, or metal foils. As the second substrate, a non-oriented film is preferably employed.

The present invention relates to a method for producing flexible polyurethane foams based on polyoxymethylene-polyoxyalkylene block copolymers. The invention also relates to the use of the flexible polyurethane foams thus produced and their use for producing furniture upholstery, textile inlays, mattresses, automobile seats, headrests, armrests, sponges, foam sheets for use in automobile parts such as roof linings, door panel upholstery, seat covers and technical components. The invention finally relates to a two-component system for producing flexible polyurethane foams.

The polyisocyanate cured product according to the present invention has an isocyanurate structure, which comprises at least one diisocyanate selected from the group consisting of an aliphatic diisocyanate and an alicyclic diisocyanate, as a unit structure, the polyisocyanate cured product having an allophanate group, and the molar ratio of the isocyanurate group to the allophanate group (isocyanurate group/allophanate group) is 99/1 to 20/80.

The present invention relates to a crosslinkable composition for forming a polyurethane coating on different types of substrate. The present invention relates in particular to a polyurethane composition comprising isosorbide as a diol chain extender, and to the polyurethane coating obtained from this composition.

The present invention relates to a crosslinkable composition for forming a polyurethane coating on different types of substrates. The present invention relates in particular to a polyurethane composition with a high biosourced monomer content, comprising isosorbide as a diol chain extender and a pentamethylene diisocyanate trimer; the invention also relates to the polyurethane coating obtained from this composition.

An object of the present invention is to provide a golf ball travelling a great flight distance on driver shots on a rainy day and having excellent spin performance on approach shots. The present invention provides a golf ball comprising a golf ball body and a paint film covering the golf ball body and composed of at least one layer, wherein an outermost layer of the paint film is formed from a paint containing a polyol, a polyisocyanate, and a carbinol modified silicone oil different from the polyol compound.
