dc.description.abstractIn this research, Mooney viscosity was tested for natural rubber (NR) from Malaysia (SMR CV60), Cambodia (SCR 10 and SCR L) and Vietnam (SVR 3L). The effect of different origins of NR, different loading of carbon black (CB) filled NR compounds, and different vulcanization systems (efficient vulcanization (EV) and conventional vulcanization (CV) systems) were studied. Origins of NR showed different cure characteristics due to molecular weight and protein content. In EV system, SCR10 possesses higher molecular weight and protein content hence give faster cure rate for both gum and filled compounds. For CV system SCR L possesses lower molecular chain but higher protein content exhibiting faster cure rate for gum compound. For effect of CB loading, higher CB loading significantly increased the physical and mechanical properties of NR compounds, but decreases fatigue life due to stability of the compound. Compounds with CV system show higher physical and mechanical properties compared to EV system, but CV system are vulnerable to heat ageing due to the breakage of polysulphidic crosslinks.en_US
