Sorbothane - a material to absorb shock and energy. Sorbothane is a proprietary, visco-elastic polymer. Visco-elastic means that a material exhibits properties of both liquids and solids.

Sorbothane is a thermoset, polyether-based, ‘super-soft’ polyurethane. It is ROHS and WEEE compliant.

Sorbothane combines shock absorption, good memory, vibration isolation and vibration damping characteristics. In addition, Sorbothane is a very effective acoustic damper and is an ideal material to absorb energy. While a wide range of materials exhibit one of these characteristics, Sorbothane combines them all in a stable material with a long fatigue life.

Sorbothane is designed as a material to absorb energy – it converts friction to heat and disperses it.

Sorbothane has a low creep rate compared to other polymers (rubber, neoprene, silicone etc.)

Sorbothane has a superior damping coefficient, over a wide temperature range compared to any other polymer.

Unlike fluid based shock absorbers or foam products Sorbothane absorbs shock for millions of cycles.

Some examples of applications using Sobothane include:


Sorbothane is widely used to isolate delicate electronics – printed circuit boards, LCDs, disk drives and other devices.

Applications include rocket launchers and wind turbines.

Shock Absorbers

Sorbothane is designed as a material to absorb energy. It does not compress and it returns to its natural shape time and time again after contraction, dilation and distortion.


Sorbothane hemispheres are used throughout the world in the highest quality audio equipment. In addition we can offer custom designed solutions to improve your system.


Sorbothane is a popular material for gaskets because of its chemical resistance, its ability to conform to irregular surfaces, its low creep and its reusability. Its natural tackiness makes it easy to install. Gaskets can be made from sheet material or produced to order.
