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..
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
