The effect on hardness and density of filling materials in NR/SBR rubber compounds

Abstract

The effects of SBR and NR compounds on characteristics of different filing were examined. Natural rubber (NR RSS3) and styrene-butadiene rubber (SBR 1502) were used as the main matrix material.  New compounds were formed by replacing the fillings in the general compound of the existing factory (SiO2, CaCO3) with 10 % blast furnace flue dust, rice husk, reclaimed rubber (recycled) and   wood ash. Comparison of the new compounds with the existing compounds revealed a decrease in hardness and density.
