ANALYSIS OF CARBON BLACK PROPORTION ON DURABILITY AND WEAR BEHAVIOR OF EPDM RUB

Mechanical Engineering

The present day scenario in the industrial sector demands high productivity and the life of rubber components. EPDM rubber is widely used in all type of non-tyre applications. Addition of filler materials enhances the properties of an elastomer by improving its mechanical properties such as the hardness, abrasion resistance, durability or the fatigue life. In order to design a product and understand the properties of the filled elastomers used in industry; it is important to understand the effect of a filler on the elastomer. This work is focused on studying the effect of composition of carbon black type on the mechanical properties of EPDM rubber characterization. Our sponsor’s problem was durability of component. It was observed that failure occur due to wear. To increase both durability and wear resistance, different tests were performed on filled EPDM rubber with two different kinds of carbon black N330 and N550. All tests were performed at room temperature. The tests include hardness tests, tensile tests, hot air aging test, wear tests, and durability test. The findings show that the combination of carbon black improves the wear resistance and durability of EPDM rubber.
