| drift |
Molecule chains of a stretched elastomer begin to slowly drift apart from each other when they or their crosslinks get damaged by too high strain or temperature. This results in an increase of steepness and long term hysteresis. Molecule chains those are not fixed by crosslinks (like eg in thermoplastics) drift around under mechanical load also without that molecules got torn apart.
