PTMEG based Casting Polyurethane prepolymer

1. PTMEG based polyurethane prepolymer is the higher level of Polyether prepolymer, they 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.
