Sorbothane Polyurethane Damping Material, 70 Durometer
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Elastomer, Unreinforced; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Sorbothane® is a thermoset, polyether-based polyurethane viscoelastic material that combines high energy absorption with faultless memory. Sorbothane turns mechanical energy into heat. As the material is deformed, the friction created at the molecular level is generated into heat. High hysteresis is then formed. The energy is moved perpendicularly away from its original plane and is pushed close to 90° out of phase from its original disturbing force. Sorbothane is used in shock/vibration mounts, stud mounts, and grommets/bushings in diverse fields such as electronics/audio equipment, noise abatement, insoles, protective sports gear, and anti-vibration gloves and wraps.
