  • Evolmer® (Acrylonitrile-co-chloroprene rubber) is a brand-new polymer, offering good resistance to oil and common chemicals, high heat and ozone resistance, outstanding flex fatigue resistance, and excellent resistance to low-temperature compression set. Evolmer® can be a candidate material for high-performance industrial applications, such as rubber rollers, seals, diaphragms, hoses, rubber linings, belts, etc. To fully explore its application potentials and commercial significance, it is of paramount importance to establish viable curing strategies and appropriate reinforcements to achieve the required balance of processability and properties. Impacts of different curing regimes on the rheological and physical properties of Evolmer® are explored. It has been seen that both the short- and long-term properties of Evolmer® are largely influenced by the different curing systems used. Effects of various grades of carbon black as reinforcing filler, with large range surface areas and aggregate morphologies on the properties of Evolmer® are also studied. The impacts exerted by the different carbon-black fillers on the cure characteristics and the mechanical properties of Evolmer® are correlated with the three key features of the carbon black: surface area, structure, and surface functional groups.
