Supersoft Urethane Sheets & Strips

Low creep rate compared to other polymers (rubber, neoprene, silicone etc.)  Superior damping coefficient over a very wide temperature range. Can absorb shock efficiently for millions of cycles.

This material is a soft visco-elastic polymer. Visco-elastic means that a material exhibits properties of both liquids (viscous solutions) and solids (elastic materials).

It has the properties of a thermoset, polyether-based, polyurethane material. The material combines shock absorbtion, good memory, vibration isolation and vibration damping characteristics.  In addition it is a very effective acoustic damper and absorber. While many materials exhibit one of these characteristics, it combines all of them in a stable material with a long fatigue life.
