Abstract:

A range of polyurethane elastomers based on di-isocyanate prepolymers of polyether, hydroxyl-terminated polybutadiene, polyester adipate and caprolactone polyols have been prepared and their ageing properties assessed under a wide variety of laboratory simulated environmental conditions, including exposure to dry air 80 to 100 C, ultraviolet radiation immersion in oil at 100 C, standard test fluid 65 C and water 50 to 100 C.
