Polyether based Casting Polyurethane prepolymer

1.Polyether based polyurethane prepolymer are recommended for applications where parts undergo dynamic stress, etc, they incur lower heat build-up. They also have advantages in high resilience, low temperature performance and resistance to water attack(hydrolysis). Polyethers also have lower viscosity and specific gravity.
