Title
(EN) HIGH STRENGTH POLYURETHANE FOAM COMPOSITIONS AND METHODS
(FR) COMPOSITIONS DE MOUSSE DE POLYURÉTHANE À HAUTE RÉSISTANCE ET PROCÉDÉS
Abstract
(EN)
Disclosed are high strength polyurethane foam compositions and methods of making them. In one aspect, the inventive polyurethane foams include strength enhancing additives comprising one or more polycarbonate polyols derived from the copolymerization of CO2 and one or more epoxides. In one aspect, the inventive methods include the step of substituting a portion of the polyether polyol in the B-side of a foam formulation with one or more polycarbonate polyols derived from the copolymerization of CO2 and one or more epoxides.

L'invention concerne des compositions de mousse de polyuréthane à haute résistance et des procédés de fabrication de celles-ci. Dans un aspect, les mousses de polyuréthane de l'invention comprennent des additifs renforçant la résistance, y compris un ou plusieurs polyols de polycarbonate, obtenus par la copolymérisation de CO2 et d'un ou plusieurs époxyde(s). Dans un aspect, les procédés de l'invention consistent à substituer une partie du polyol de polyéther, du côté B d'une formulation de mousse, par un ou plusieurs polyols de polycarbonate obtenus par la copolymérisation de CO2 et d'un ou de plusieurs époxyde(s).
