dc.description.abstract | The degradation behaviors of EPDM (ethylene-propylene diene monomer) rubbers used for automotive radiator hoses subjected to thermo-oxidative and electrochemical stresses were studied. As a result of the thermo-oxidative aging tests, the IRHD (international rubber hardness degrees) hardness of the rubber specimens increased, while their elongation at break decreased much. A slight increase in crosslink density indicated that changes in the properties were caused by the concentration of carbonyl groups in the skin layer. For the electrochemical degradation (ECD), the weight of rubber specimens increased whereas their elongation and hardness much decreased because water solution penetrated into the skin part. There was little change in crosslink density. Formation of many chain scissions and thus microvoid networks in the skin layer induced the swelling behavior leading to a linear reduction of hardness versus the weight increase. | - |
