The effect of different coagents on the physico‐chemical properties of NBR/HDPE composites reinforced with 40 phr (part per hundred part of rubber by weight) HAF carbon black and cured with accelerated electrons was investigated. The coagents N , N ′‐methylene bisacrylamide (MBAAm) and trimethylol propane trimethacrylate (TMPTMA) were used at a constant content of 10 phr. The physico‐chemical properties such as tensile strength, tensile modulus at 50% elongation ( M 50 ), elongation at break ( E b ), hardness, soluble fraction (SF), swelling number (SN), electrical conductivity, and thermal properties were studied. The results obtained showed that the TMPTMA as a coagent is more effective than MDA in enhancing the mechanical and physical properties of NBR/HDPE vulcanized composites. POLYM.
