Abstract：The effect of blend ratio, compatibilizer content, method of mixing on the properties of NBR/EPDM blends were studied. The result shows that EPDM should enhance aging properties and the electric insulation of NBR, the compatibilizer could improve the mechanical properties. The mechanical properties achieves best when added 10 phr, but not excessive. The method of after passing through the respective allocated proportion, mixes again to blends over-all properties is better than the ordinary method.
