5.1 Mechanisms

The main causes of rubber ageing, alone or in combination, are :

  • thermal aging ;

  • thermo-oxidative ageing (temperature and oxygen) ;

  • mechanical ageing (stress and temperature) ;

  • ozone action;

  • the action of light;

  • the action of water or organic derivatives

By way of illustration, when a rubber is subjected simultaneously to thermomechanical stress in the presence of oxygen, the reaction mechanisms are :

  • thermomechanical effect (figure
