Influence of fillers on NR/SBR/XNBR blends. Morphology and wear

The blends of carboxylated acrylonitrile butadiene rubber (XNBR), styrene-butadiene rubber with high styrene content (SBR) and natural rubber (NR) were prepared with different types of carbon black. The effect of filler on morphological and wear characteristics was studied. Intermediate super abrasion furnace (ISAF) carbon black showed improve result on curing study and mechanical properties by reacting at the interface between XNBR, SBR and NR matrix. Blends containing ISAF carbon black showed high abrasion resistant properties against Du-Pont abrader, DIN abrader and different mining rock surfaces and also was found to be the toughest rubber against all types of rock.
