Water Diffusion in Natural Rubber Vulcanizates: Effect of Ingredient Loading on Swelling and Mechanical Properties

Abstract:

The effect of compounding ingredients to swelling and mechanical properties of vulcanized natural rubber (NR) in deionized water at 80°C was investigated. Rubber sheets are compounded according to a fractional factorial design of experiment, where ingredients are treated as factors varied at two levels of loading. Results show that sulfur, used oil, calcium carbonate (CaCO₃), reclaimed rubber, asphalt, diphenyl guanidine (DPG), mercaptobenzothiazole (MBT), and mercaptobenzothiazole disulfide (MBTS) are some of the significant ingredients of the formulation affecting the material properties of vulcanized NR. Among the compounding ingredients, sulfur and used oil are the most influential and consistent factors which affect the swelling and tensile properties of vulcanized NR during water diffusion.
