The study reports features of natural rubber and styrene-butadiene latices blends, and the influence of dithiocarbamate accelerated sulphur cure system on the properties of the cured rubber blends. Blend NR/SBR = 80/20 (C) shows some synergistic effect in mechanical properties. Most of the mechanical properties decrease with increased SBR in blends. The crosslink density is calculated using swelling measurement and correlated with vulcanized properties. The homogeneity of NR/SBR latices blends was determined by differential scanning calorimetry.
Key words: natural rubber latex, styrene-butadiene latex, blends, mechanical properties, crosslink density, differential scanning calorimetry.
