| Abstract | The objectives of the research were to study the effect of HAF/SRF black ratio and the loading of sulfur on vulcanization characteristic, swelling behaviour and compression set of NBR vulcanizates. The ratio of HAF/SRF were 0/70; 10/60; 20/50; 30/40; 35/35; 40/30; 50/20 and 70/0 phr, respectively. The observation of this research consist of curing characteristic, morphology property and swelling equilibrium. Curing characteristic was determined from cure rate index (CRI), vulcanizates morphology was studied by SEM and swelling equilibrium was conducted by immersion test using benzene. The data were analyzed qualitatively to see the respond of the variable on physical properties. The curing characteristic of double filler vulcanizates was higher than those with single filler. Solvent uptake for double filler present in between to those with HAF or SRF. All of vulcanizates indicate the anomalous mass tranfer, with n>0,5 and constant k showed the same trend. The intrinsic diffusivity (D*), sorption and permeation coefficient showed similar trend and the maximum was obtained by the ratio HAF/SRF 0/70. |
