Evaluation of EPDM Addition in NR/BR Compound by Reactive Mixing

Improvements in the properties of ordinary sidewall compound (NR/BR) with the addition of EPDM by reactive processing method were evaluated. The results show that ozone resistance of these sidewalls was improved with increased addition of EPDM. Also the tensile strength and elongation-at-break were...

Description
Summary:Improvements in the properties of ordinary sidewall compound (NR/BR) with the addition of EPDM by reactive processing method were evaluated. The results show that ozone resistance of these sidewalls was improved with increased addition of EPDM. Also the tensile strength and elongation-at-break were increased in comparison with NR\BR\EPDM compounds that were made by non-reactive processing. SEM Photographs show that the reactive processing method helps to improve the compatibility of these three elastomers compared with NR\BR\EPDM system made by non-reactive processing. The results of fatigue-to-failure and tear resistance show that compounds prepared by reactive processing have a better property in comparison with non-reactive samples. Tensile and elongation-at-break of the reactive samples were superior to the non-reactive samples after aging.
