The effect of carbon black concentration on the stress-strain and creep characteristics of NBR/EPDM blend was studied. The mechanical parameters obtained from the stress-strain and the creep measurements may suggest the formation of a compact structure around the concentration of 40 phr HAF black. The stress- strain behaviour of the composites under test is fairly consistent with the standard linear solid model. All the obtained data from the creep measurements are discussed within the frame of Burgers model.
