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.
摘要翻译：提供了包括聚氨酯预聚物组合物，催化剂和推进剂的聚氨酯泡沫。聚氨酯预聚物组合物由包含基于聚氨酯预聚物组合物约1％至约70％（重量）的异氰酸酯反应性组分和约1％至约70％的异氰酸酯组分的配方制成基于聚氨酯预聚物组合物的重量％。异氰酸酯组分包括基于异氰酸酯组分约1至约100重量％的甲苯二异氰酸酯缩二脲。异氰酸酯反应性组分包括一种或多种多元醇。聚氨酯预聚物组合物在50℃下的粘度小于约10,000mPa·s，基本上不含单官能活性组分。聚氨酯预聚物组合物还包括少于约1重量％的甲苯二异氰酸酯缩二脲的游离异氰酸酯单体含量。
