Durometer Range Suggestions And Physical Considerations
There are times when, when researching a project, you need some qualifying information to get started. Below, we have included a chart with suggested common durometer ranges for various applications. In conjunction with that, we have listed the physical properties that you should consider for each use. However, not all durometer ranges and considerations may apply to your application. Contact PSI Urethanes to get expert guidance for your application.
Suggested Durometer Ranges
