| Abstract | ||
| In the current research (which is done in the laboratories of Babylon Tires Factory), Studying the effect of molybdenum trioxide upon the characteristics of curing system of styrene- Butadiene rubber (SBR) has been carried out by using Oscillating Disk Rehometer according to the ASTM D-2084 specification. The Results showed that the effect of addition (Molybdenum trioxide) to styrene butadiene rubber in proportions of (0, 7.5,15,22, and 28) phr (per hundred percent). Molybdenum tri-oxide uses to enhance the hardness, the tensile strength and Reometric properties of the rubber. The result showed that the cure time and scorch time decreased when torsion stress and filler content increased also the tensile strength and hardness advanced with the filler content increased. The hardness developed significantly from (62) to (68) shore (A) when molybdenum trioxide added therefore the rebound and elongation decreased. | ||
