Clieraical Advantages for tlie Elastomer Producer • no unsaturation • no ester linkage • no secondary hydroxyls
Urethane elastomers are prepared by either the pre-polymer or one-shot method by reacting Polymeg (a linear ether glycol) with an excess of diisocyanate to promote cross-linking. The mechanical properties of the elastomers are outstanding. Properties can be tailored to fit specific applica-
Physical Advantages for the Elastomer Producer • low viscosity and easy processing characteristics • low hysteresis loss • excellent moisture resistance • good abrasion resistance • remarkable resiliency • excellent low temperature flexibility • high moisture vapor transmission
