Effect of process oil on filled styerene butadiene rubber vulcanizates / Khairunnisa Liyana Abd Hamid Ridza

Theoretically, unfilled rubber barely gives poor mechanical properties. The use of filler would increase the mechanical properties. In this study, reinforcing material used is carbon black (HAF N330). For better dispersion of filler, processing oil is required during rubber compounding. The processing oils that added are aromatic oil, paraffinic oil, and naphthenic oil. The goal of this investigation is to evaluate the mechanical properties of compounds. In determining the changes in the mechanical properties of SBR, some testing is implemented. The testing are tensile test, hardness test, and aging test. Moreover, density and cross-link density of compounds also determine. As a result, carbon black does improve the mechanical properties of vulcanized SBR. Although paraffinic acts as oxidation resistance it also imparts lower mechanical properties.
