HIGH TEMPERATURE POLYURETHANE/UREA ELASTOMERS

The present invention relates to molded polyurethane/urea elastomers, and specifically to improved polyurethane/urea elastomers having high temperatur e stability to about 140-150 ~C and low temperature flexibility at about -35-( - 40) ~C, for use in dynamic applications. These elastomers are partic...
