Beschreibung
Zusammenfassung:	A polyurethane foam is prepared with certain polytetrahydrofurans and optional polyether polyols. The polyurethane foam is characterized by low hardness increase at low temperature as compared with conventional polyurethane foam, and is suitable for the use in product which can be exposed to low temperature such as snow boot. Se prepara una espuma de poliuretano con determinados politetrahidrofuranos y polioles de poliéter opcionales. La espuma de poliuretano se caracteriza por un bajo aumento de la dureza a bajas temperaturas en comparación con la espuma de poliuretano convencional y es adecuada para el uso en productos que se pueden exponer a temperaturas bajas, tales como botas de nieve.
