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.
