CA 2233257

The invention relates to compositions and method for producing energy absorbing, water blown, rigid polyurethane foams. The resulting polyurethane foams are low density, predominately open celled foams which exhibit a relatively constant consistency of compressive strength over deflectors. Such foams are suitable as lightweight alternatives to traditional energy absorbing applications.

Cette invention concerne des compositions de mousse rigides de polyuréthane, absorbant l'énergie et soufflées à l'eau, et une méthode pour les produire. Ces mousses de polyuréthane, de faible masse volumique et avant tout poreuses, possèdent une consistance de résistance à la compression relativement constante lorsqu'elles sont placées sur des déflecteurs. De telles mousses sont utiles comme produits de substitution légers pour des applications classiques où de l'énergie est absorbée.
