Abstract

L'invention concerne un polyuréthane exempt de solvant qui est un produit de polycondensation des composants suivants : (a) un mélange diisocyanate binaire de diphénylméthane diisocyanate et d'isophorone diisocyanate, (b) un polyester polyol présentant un point de fusion de 30 à 35 °C, un poids moléculaire compris entre 300 et 1500 et une fonctionnalité de 2, et (c) un polyester polyol présentant un point de fusion de 30 à 35 °C, un poids moléculaire compris entre 300 et 1500 et une fonctionnalité supérieure à 2. L'invention concerne également un processus destiné à préparer le polyuréthane exempt de solvant, et l'application du polyuréthane exempt de solvant à la préparation de produits de film par procédé d'imprégnation. Le produit de film de polyuréthane produit par le procédé d'imprégnation présente des performances améliorées telles qu'une propriété de glisse, une propriété mécanique et une propriété élastique, par rapport au produit correspondant de l'art antérieur. L'invention concerne également l'application du polyuréthane exempt de solvant à la préparation de gants.
