聚氨酯泡沫广泛用于许多工业应用中，包括汽车、软垫家具和床垫、建筑用绝缘板。根据所需的应用，聚氨酯泡沫可以使用许多不同的化学品和配方生产。软质聚氨酯泡沫塑料的物理性能取决于其组成。它们将与所用多元醇的特性、化学计量（多元醇/异氰酸酯）、催化剂和表面活性剂的量以及水含量（以及密度）密切相关。由于其化学性质，聚氨酯非常易燃。聚氨酯泡沫塑料的可燃性是一个重要的工业问题。本文研究了常规聚氨酯软质泡沫塑料的组成对其热稳定性和燃烧性能的影响。(c)2004爱思唯尔有限公司保留所有权利。
Polyurethane foams are widely used in many industrial applications, including automotive, upholstered furniture and mattresses, insulating panels for building. Depending on the desired application, polyurethane foams can be produced using many different chemicals and formulations. The physical properties of flexible polyurethane foams depend on their composition. They will be closely related to the characteristics of the polyol used, to the stoichiometry (polyol/isocyanate), to the quantity of catalysts and surfactants and to the water content (and so to the density). By its chemical nature, a polyurethane is very flammable. The flammability of polyurethane foams is an important industrial issue. This paper deals with the influence of the composition of conventional flexible PU foams on their thermal stability and fire behaviour. (c) 2004 Elsevier Ltd. All rights reserved.
