Abstract
This research was aimed at gaining the compound rubber of dock Vender formula which has the characteristic of optimal tensile strength after aging 70 + 1oC within 3 x 24 hours and the optimal elongation at bre ak before aging. This research used the amount of car bon black formula with variation : 40,45,50,55,60,65, and 70 parts for each 100 partsof rubber. The research showed that using the formula 40 : 100, the optimal tensile strength after aging 70 + 1oC during 3 x 24 hours resulted the average tensile st rength 19,79 newton/mm2. Where as the characteristic of the optimum elongation at break was gained at formula 40 part with the average elongation break 682,98% . The result showed that the elongation break aft er aging and elongation at break after aging fulfilled the specification of SII 2281 88 dock Vender.
