Influence of the blend composition in the internal friction of NR/SBR compounds

Mechanical dynamic measurements were used in this work to analyze the behavior of cured, carbon black-filled NR/SBR blends using a sulfur/accelerator system. The loss tangent (tan δ) of the compounds was studied in the frequency range between 10-3 and 10 Hz and temperatures between 80 and 260 K. Mea...
