The present work is intending to elaborate high performance lubricate resistant rubber crop based on NBR, PVC and CR blends expected utilized in automobiles industry. The blend vulcanizates are judged by rheological, physical and machinelike characteristics.The characteristics of the created blends either binary blends (NBR/PVC or PVC/CR) or having three of something blends (NBR/ PVC/CR) were investigated by rheological properties, machinelike analysis and lump in oil and toluene. Since many different substitute components can come into touch with oils and greases, lubricate-resistant polymeric matters are crucial for the automotive sector. The synthetic makeup of elastic, specifically its electro-habitual skepticism and crystallinity, is crucial in the production of goods that are opposing to oil. It was found that the inclusion of PVC in the blend compositions leads to the decrease in standard of swelling, the penetration rate and the average spread coefficient. On the other hand the final tensile strength (UTS), the hardness and strain strength were increased. This was assign to the plastic nature of PVC, next to its supplementary behavior as filler. The crosslinking mass in the blend vulcanizates under investigations was contingent upon Flory-Rehner and Mooney-Rivlin [Stress/Strain] equations. The diffusion in elastic is important, cause it is always used to foreign fragments, which may be smoke, liquids, or whole. The study of diffusion of oils or organic solvent in rubber crop is very serious from experimental and economic points of view. The oil opposing rubbers are main in automotive industry. Oil resistance is the alternate of the degree of lump in oil and is governed apiece competition middle from two points the driving force towards dissolution of the elastic in the low-molecularweight oils and the intermolecular forces of the polymer form. The additional physical crosslinks (in the way that entanglements, etc.), in addition to the synthetic crosslinks established by swelling in toluene, maybe blamed for the bigger values of crosslinking density stated by Mooney-Rivlin. This study demonstrated the good acting oil resistance of NBR/PVC blends, that can be submitted to the automotive industry.
