The mechanical properties, compatibility, flame retardancy property, hot-air ageing resistance of hydrogenated nitrile-butadiene rubber (HNBR) / chloroprene rubber (CR) blends were investigated. With increasing CR, stress at 100% elongation, shore A hardness, limited oxygen index of HNBR/CR blends increased, while the tensile strength, hot-air aging resistance of the blends decreased. Differential scanning calorimeter (DSC) revealed that it’s incompatible with both HNBR and CR before vulcanization, however they became compatible completely after vulcanization as indicated by Dynamic Mechanical Analysis (DMA).
