  1. Stress-relaxation for TPV Materials

  2. Long term stress-relaxation (to be updated)

  3. Measured at DADC SBR (60 shore A) NR (50 shore A) EPDM (50 shore A) most stable Sarlink X9156B (60 shore A) Stress-relaxation data at 80°C

  4. Stress relaxation physical stress relaxation at low temperatureslog P(t)/P(0) = -C . log(t)chemical stress relaxation at higher temperaturesP(t)/P(0) = SUM {Ai . e -K(i).t } What happens in the material: physical relaxation, thermal and oxidative degradation, continued cross linking TPV: mainly physical stress relaxation over broad temperature range
