Hydrogenated natural rubber is a potential material to be used as good heat-, UV-, oxidation resistance material. Hydrogenation natural rubber (NR) could be performed in colloid system as latex using hydrazine hydrate and hydrogen peroxide system in water, as hydrogen source system. Therefore, the latex system must be stable to mediate the effective hydrogenation reaction. In this study, we use measurement of turbidity and viscosity of natural rubber latex system to assess the stability of the rubber particles. Composition of latex particles was varied between 20 and 30% (w/w), temperature 25 °C to 70 °C, time 1 h–5 h and agitation condition 60–200 rpm. The optimum stability of latex was obtained at 1 phr of SDS as anionic surfactant, 20% (w/w) of rubber concentration and 100 rpm of agitation rate during 3 h at 25 °C.
