Processing, cure characteristics, and mechanical properties of NR/EPDM blends were studied
as a function of blend ratio and compatibilizer concentration. Mooney viscosity decreased with
increase in EPDM content in the NR/EPDM blend ratios whereas cure time showed an increase.
The mechanical properties of the NR/EPDM blends are found to be influenced by the blend ratio.
Tensile strength and elongation at break decreased with increase in EDPM content. However, the
change of 100% modulus with increase of EPDM content in the NR/EPDM blend was quite small
