Various technological properties such as tensile, resilence, hardness, compression set, specific gravity, cross-link density and resistance to oil were measured and compared. It is advantageous to use SP rubber in place of NR in the above blends probably due to higher cross-link density in the SP rubber component when compared to NR. It may be possible to use the ternary blends of SP/PVC?NBR in manufacture of injection modable and recyclable products due to their thermoplastic nature ER -
