High and low temperature performance of various urethane elastomers is discussed in terms of compatible/incompatible polymer theory. The influence of polyol molecular weight, low molecular chain extender and isocyanate are presented and discussed in terms of their effect on the modulus/temperature sensitivity of the elastomers studied.
