Supersoft Urethane Sheets / STxx Series


      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.

The super soft urethane material is a soft visco-elastic polymer. Visco-elastic means that a material exhibits properties of both liquids (viscous solutions) and solids (elastic materials).
Our super soft urethane 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, the super soft urethane combines all of them in a stable material with a long fatigue life.
