De Silva, K.G.K.Karunanayake, L.Muttukkrishnan, K.2012-06-252012-06-251999Journal of the Rubber Research Institute of Sri Lanka82pp.1-7https://dl.nsf.gov.lk/handle/1/8714The advantage s of using superior processing(SP)rubber in place of natural rubber (NR) in blends with NBR and NBR/PVC is discussed here in derail.various technological properties such as tensile,resilience,hardness,compression set,specific gravity,cross-lind 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 moldable and recyclable products due to their thermoplastic natureChemical TechnologySuperior processing rubberPoly vinyl chiorideNatural rubberTechnological propertiesPolymersAcrylonitrile butadiene rubberArticle
