The influence of CB loading on thermal aging resistance of SBR and NBR rubber compounds under different aging temperature

Aging temperatures play important role in changing the mechanical behavior of rubber, so thermal aging test under different temperatures was carried out to investigate the effect of aging temperatures on the tension, compression and hardness properties of styrene butadiene rubber (SBR) and nitrile butadiene rubber (NBR) compounds filled with different carbon black (CB) loading. The obtained results of five different compositions for SBR and NBR with 0, 20, 30, 50 and 70 phr of CB were compared. The dependences of the mechanical properties on aging temperature and CB loading were found.
