Description:
Viscoelasticity is a term used to describe materials that exhibit both viscous flow and elastic spring back when a force is applied to them. Viscous flow is a time dependent phenomenon, and an elastic response is instantaneous after a stress has been removed from a material. Viscoelastic materials exhibit both of these properties. The rigid and flexible domains of polyurethanes contribute to their viscoelastic behavior. This webinar is designed to give a fundamental understanding of viscoelasticity as it is related to polyurethane morphology and the isocyanate and polyol building blocks which make up polyurethane polymers.
