Abstract The shear viscosity, creep and constant rate transients have been measured for 0.20 volume fraction compounds of an EPDM with calcium carbonate, carbon black, silica zinc oxide similar particle size at 100°C. Measurements made in a sandwich instrument, pressurized rotational rheometer capillary cover nine decades rate. All the exhibit enhanced viscosities yield values; i.e. there are stresses below which is no flow. greatest values increased carbonate oxide. More extensive studies were EPDM-calcium system, where it was shown that, increasing reduces viscosity values. Further, surface treating stearic acid signifcantly value corresponding compound.
