(JA) 注型熱硬化型ポリウレタンエラストマー
Abstract
(EN)
This cast-molded heat-curable polyurethane elastomer is obtained by reacting at least a polycarbonate polyol (A), a polyisocyanate (B), and a polyrotaxane (C) and can, if necessary, include 0%-30% by mass of an inorganic material (D), relative to the total mass of polycarbonate polyol (A), polyisocyanate (B), polyrotaxane (C), and the inorganic material (D). The mass addition ratio of the polyrotaxane (C) is 1%-10% by mass relative to the total mass of polycarbonate polyol (A), polyisocyanate (B), polyrotaxane (C), and the inorganic material (D); the viscosity of the polyrotaxane (C) is no more than 5,000 cP at 120°C; or the dilutable rate for the polyisocyanate (B) is no more than 0.4.
(FR)
 L'invention concerne un élastomère de polyuréthane moulé de type à durcissement à chaud obtenu par mise en réaction d'au moins: (A) un polyol de polycarbonate; (B) un polyisocyanate; et (C) un polyrotaxane. Si nécessaire, cet élastomère de polyuréthane moulé de type à durcissement à chaud peut contenir de 0 à 30% en masse d'une substance inorganique (D), par rapport au total de la masse de polyol de polycarbonate (A), de polyisocyanate (B), de polyrotaxane (C) et de cette substance inorganique (D). Cet élastomère de polyuréthane moulé de type à durcissement à chaud se caractérise en ce que le taux d'addition en masse de polyrotaxane (C) par rapport au total en masse de polyol de polycarbonate (A), de polyisocyanate (B) et polyrotaxane (C) et de la substance inorganique (D) est compris entre 1 et 10% en masse, ou en ce que la viscosité du polyrotaxane (C) est égale ou inférieure à 5000cP à 120℃, ou encore en ce que le rapport possible de dilution du polyisocyanate (B) est égal ou inférieur à 0,4.
