Better than rubber, neoprene or silicone*
Sorbothane is a proprietary, visco-elastic polymer that has a very high damping coefficient. Visco-elastic refers to any material that exhibits properties of both liquids (viscous solutions) and solids (elastic materials). Because visco-elastic behavior is desirable in shock and vibration applications, many materials claim to be so. Technically, they’re correct, but only because they have trace “visco-elastic” properties.
Sorbothane® can absorb up to 94.7 percent of shock energy.
Sorbothane® combines shock absorption, good memory, vibration isolation and vibration damping characteristics. While many materials exhibit one of these characteristics, Sorbothane® combines all of them in a stable material with a long fatigue life. Sorbothane® has a low creep rate (refers to the time-dependent deformation of a material under a certain applied load) compared to other polymers* (rubber, neoprene, silicone, etc.)
Absorbs millions of shocks
Sorbothane® has a superior damping coefficient, over a very wide temperature range, compared to any other polymer. Unlike fluid-based shock absorbers or foam products, Sorbothane® absorbs shocks efficiently for millions of cycles. Sorbothane® eliminates the need for metal springs to return the system to its equilibrium position after absorbing a shock.
