Table 2 shows the Mooney viscosity values and vulcanization characteristic of the EPDM blends with white
fillers. The Mooney viscosity of the EPDM blend 4 (104 MU) was comparable with reference blend (110 MU).
The other EPDM blends showed lower Mooney viscosity values, in the range from 88 to 95 MU, what is related to
different stiffness of blends.
