Technical Details & Test Data
- Compression Fatigue
The most visible signature of fatigue is compaction – the material fails to recover to its original thickness after repetitive or long term compression. Compaction is quantified as “compression set”, a relationship between the original thickness (T) and the compacted thickness (t), expressed as % loss. Compression set is the result of plastic deformation of cell walls and the reduced resilience of damaged cells. R-Series performance is exceptional with virtually zero compression set or degradation of cellular structure providing a superior alternative for many demanding applications.
- Stress Relaxation
Defined as a gradual decrease in stress with time under a constant deformation or strain. This polymer behavior is studied by applying a constant deformation to the specimen and measuring the stress required to maintain that strain as a function of time. Basically, it quantifies the stress lost by the material over time while maintaining a constant strain. R-Series maintains this stress much longer than standard foams, making it an ideal performance material for demanding gasket and die ejection applications.
- Hysteresis Loss
The measure of the energy lost or absorbed by a foam when deflected by a specified strain and immediately recovered at the same strain rate to its original thickness, it is the area between the loading and unloading curves on a hysteresis loop. R-Series, with a resilience of 50% extraordinary compression resistance properties, exhibits very low hysteresis loss of just 15% making it an advantaged material for high energy return applications.
