Abstract

Compared with NR and HNBR compounds, the blend properties of NR/HNBR were studied. The heat, oil and ozone resistance of NR compounds were improved by blending HNBR, and these effects were more clearly revealed with elevating temperatures. For the overall stabilities of the compounds, it was resonable to use the carbon black under the 60phr. In the EV systems, high-saturated NR/HNBR and HNBR compounds showed similar total crosslink density in comparison with NR compounds. Interaction parameters calculated by stress-strain method showed widely varied value.
