Abstract

Articles en polyuréthanne, durs, résistants aux chocs avec une température de déformation à la chaleur élevée. Le polyuréthanne est obtenu à partir d'un polyisocyanate cycloaliphatique, d'une matière de bas poids moléculaire contenant des hydrogènes actifs et éventuellement d'un polycarbonate diol. Le pourcentage en poids des fractions d'uréthanne et la densité de réticulation sont soigneusement réglés de manière à assurer un équilibre convenable des propriétés physiques, notamment entre la dureté, la souplesse et la temperature de déformation à la chaleur. Les articles en polyuréthanne sont particulièrement utiles pour des applications de vitrage, telles que le vitrage dans l'aéronautique.
