This paper attempts to show that, activated by adding different loading levels of zinc oxide (ZnO). to mix and distribute the elements of the rubber compound. MV rheometer employed to determine the properties of th 6 min. The curing process carried out using the hot press at a temperature of 180°C and pressure of 10 bars. Results show that the addition hundred parts of rubber (phr) scorch time ,curing time with particularly at 2 and 4 phr modulus of elasticity at 300% elongation, hardness and compressio phr represent the best loading level of the ZnO, which had more effect on the aging and mechanical properties. especially when the retention percentage of the properties after the Key words: EPDM, Zn Properties. This paper attempts to show that, the ethylene-propylene-diene monomer (EPDM) activated by adding different loading levels of zinc oxide (ZnO). A two to mix and distribute the elements of the rubber compound. MV-ODR rheometer employed to determine the properties of the rubber compound at 180 . The curing process carried out using the hot press at a temperature of 180°C and pressure of 10 bars. Results show that the addition of the (2,4,6,8,10) hundred parts of rubber (phr) ZnO into the EPDM elastomer guides to reduc with increasing the Max.Torque and cure rate index (CRI), phr. Furthermore, an improvement in the tensile strength and modulus of elasticity at 300% elongation, hardness and compression set seen. 2 and 4 phr represent the best loading level of the ZnO, which had more effect on the aging and mechanical properties. In addition, the rubber compound becomes more stiffness, especially when the retention percentage of the properties after thermal aging is low.
