摘要： Polyurethane foams including a polyurethane prepolymer composition, a catalyst, and a propellant are provided. The polyurethane prepolymer composition is produced from a formulation that includes an isocyanate reactive component in an amount of from about 1% to about 70% by weight based on the polyurethane prepolymer composition and an isocyanate component in an amount of from about 1% to about 70% by weight based on the polyurethane prepolymer composition. The isocyanate component includes toluene diisocyanate biuret in an amount of from about 1 to about 100% by weight based on the isocyanate component. The isocyanate reactive component includes one or more polyols. The polyurethane prepolymer composition has a viscosity of less than about 10,000 mPa*s at 50° C. and is substantially free of monofunctional reactive components. The polyurethane prepolymer composition also includes a free isocyanate monomer content of the toluene diisocyanate biuret of less than about 1% by weight.

摘要： A process is disclosed for producing polyurethane-polyisocyanurate-fiber composite parts, wherein a composition comprising polyisocyanate, a mixture obtainable by introducing an alkali metal salt or alkaline earth metal salt into a compound R—NH—CO—R′ containing urethane groups, with R′ being not hydrogen and/or not COR″, a compound containing one or more epoxide groups, polyetherol having an average functionality of 1.8 to 5.0 and a hydroxyl number of 200 to 500, a chain extender, fibrous reinforcing agents and optionally further additives form a reaction mixture. The reaction mixture is applied to the fibrous reinforcing agent and caused to react to form the polyurethane-polyisocyanurate-fiber composite part. Further disclosed is a polyurethane-polyisocyanurate-fiber composite part producible by such a process, and also the use of a polyurethane-polyisocyanurate-fiber composite part as a bodywork component of vehicles, such as bumpers, fenders or roof parts, or as structural or semistructural components for vehicles or wind turbines.

摘要： Clear polyurethane fiber reinforced composites are produced by a pultrusion process with a polyurethane-forming system that includes: (a) a clear, aliphatic polyisocyanate having a viscosity at 25° C. of no more than 1000 centipoise, (b) a colorless polyol component comprising an amine-initiated polyol having a molecular weight of from about 150 to about 400 and an OH functionality greater than or equal to 3, and (c) a catalyst. These fiber-reinforced composites are characterized by both excellent weathering characteristics and excellent physical properties.
