Carbon black (CB) is used to enhance the mechanical properties of styrene butadiene (SBR) and nitrile butadiene (NBR) rubber compounds compared with unfilled compounds. In this paper the effect of carbon black loading on the swelling and compression set behavior of SBR and NBR compounds was investigated. The obtained results of five different compositions for SBR and NBR with 0, 20, 30, 50 and 70 phr of CB were compared. From the current investigation it was found that, the increase in carbon black loading inherent with drastically reduction in swelling percentage while the compression set increases in both SBR-filled compounds and NBR-filled compounds, This behavior is more pronounced in NBR filled compounds than SBR filled compounds. This investigation clearly distinguishes the influence of conditioning environment to the properties under study.
