Summary:In this study, the influence of the organoclay (OC) nano-fillers (Cloisite 15A (CE15A), Cloisite 20A (CE20A), and Cloisite 30B (CE30B)) on the cure and swelling behaviors, compression set, abrasion resistance, and mechanical properties of a blend of 50/50 ethylene-propylene-diene monomer and acrylonitrile-butadiene rubber (EPDM/NBR) has been examined. It has been noted that the maximum torque values increase as filler loading increases. Comparing filled nanocomposites to unfilled samples, it has been observed that filled systems have a lower tendency to absorb solvent. Due to improved filler reinforcement, nanocomposites reinforced with CE30B showed the least solvent uptake across OC filled systems. The morphology of the CE30B-filled samples was more homogeneous when compared to the other (CE15A and CE20A) filler-reinforced nanocomposites. The mechanical properties of the CE30B-filled samples, followed by those of the CE20A and CE15A-filled systems, improved the most. This has been explained by CE30B OC's increased interaction between nanofiller and rubber matrix. Mechanical testing experimental results have been contrasted with various theoretical models.
