Pengaruh Karet Alam Hidrogenasi terhadap Ketahanan Oksidasi dan Ozon Barang Jadi Karet

Abstract

This aim of this research was to determine the effects of using hydrogenated natural rubber to the oxidation and ozone resistance in producing rubber goods, especially motorcycle grip handle that fulfill the standard requirement. The experiment was done using rubber compound mixture of RSS, EPDM, and RHG with different ratio formula. The result show that the addition of natural rubber (RSS), synthetic rubber (EPDM), and hydrogenated rubber RHG) had significant effect on the visual test, hardness, tensile strength, tear resistance, density, and ozone. The result of these compounds shows that the best rubber compound for grip handle is the formulation which fulfills the qualification of national standard of Indonesia for motorcycles grip handle, SNI 06-7031-2004 is the formula with natural rubber 70 phr and hydrogenated rubber 30 phr. This formulation fulfill the qualification for visual test which is not defect, hardness 72.85 shore A, tensile strength 89.75 kg/cm2, tear resistance 34.75 kg/cm2, density 1256.23 g/cm3, and ozone resistance, 25 phm, 20% strain at 40 oC for 48 hours
