    • A flexible polyurethane foam comprises the reaction product of an isocyanate component and an isocyanate-reactive component in the presence of a blowing agent. The isocyanate component comprises a polymeric diphenylmethane diisocyanate component and a monomeric diphenylmethane diisocyanate component. The monomeric diphenylmethane diisocyanate component comprises 2,4′-diphenylmethane diisocyanate and 4,4′-diphenylmethane diisocyanate. The isocyanate-reactive component comprises a polyether polyol having a molecular weight of from about 700 to about 20,000 and a plurality of terminal caps which are substantially free of ethylene oxide groups. The flexible polyurethane foam is substantially free of supplemental flame retardant additives and exhibits flame retardance under flammability tests according to California Technical Bulletin 117 regulations.
    • 柔性聚氨酯泡沫包括异氰酸酯组分和异氰酸酯反应性组分在发泡剂存在下的反应产物。 异氰酸酯组分包括聚合二苯基甲烷二异氰酸酯组分和单体二苯基甲烷二异氰酸酯组分。 单体二苯基甲烷二异氰酸酯组分包括2,4'-二苯基甲烷二异氰酸酯和4,4'-二苯基甲烷二异氰酸酯。 异氰酸酯反应性组分包括分子量为约700至约20,000的聚醚多元醇和基本上不含环氧乙烷基团的多个终端帽。 柔性聚氨酯泡沫基本上没有补充阻燃添加剂,并且根据加利福尼亚技术公报117规定在可燃性测试下显示出阻燃性。
