Which Durometer Should I Use For My Application

Durometer Range Suggestions And Physical Considerations

There are times when researching for a project, you need some qualifying information to get you started.  Below, we have included a chart with suggested durometer ranges for various applications.  In conjunction with that, we have listed physical properties that you should consider for each use.

Suggested Durometer Ranges

Index of Physical Considerations

  • A: Tear Resistance
  • B: Compression Set
  • C: Rebound (Resilience)
  • D: Abrasion Resistance
  • E: Load Bearing Ability
  • F: Chemical/Water Resistance
  • G: Heat/Cold Resistance
  • H: Frictional Properties
  • I: Ability To Handle Dynamic Forces
  • J: Shock Absorption
