DLR Elastomer Engineering Ltd Sorbothane - Durometer 30 (Shore 00)

DLR Elastomer Engineering Ltd Sorbothane - Durometer 30 (Shore 00) is one of our polyurethane products. Sorbothane provides good vibration isolation and vibration damping characteristics, making them a very effective acoustic damper. This material can also be bonded to other materials such as PTFE & metals.

orbothane is a proprietary, viscoelastic polymer. Sorbothane is a thermoset, polyether-based, polyurethane material. In addition to being viscoelastic, Sorbothane also has a very high damping coefficient. 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 compared to other polymers (rubber, neoprene, silicone, etc.)

  • Sorbothane has a superior damping coefficient, over a very wide temperature range, compared to any other polymer
  • Sorbothane’s operating temperature range is -20° to +160° Fahrenheit (-29° to 72° Celsius)
  • 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

Can be compounded for resistance

Note

* - Reduced strength and damping up to 200°F. Increased spring rate down to glass transition temperature.

** - Transmission loss increases with frequency.

*** - Burns but self-extinguishing when flame removed.
