UBE ETERNATHANE® low viscosity polycarbonate-based urethane prepolymers can be handled in manufacturing processes with limited raw materials to use due to the viscosity where standard polycarbonate-based countertypes are out of range. Using polycarbonate-based urethane prepolymers will allow manufacturers to produce polyurethane elastomers with maximized hydrolytic, solvents and chemical resistance, abrasion and scratch resistance as well as optimized properties retention.
