Ternary rubber composites NR/SBR/NBR

Effect of Filler Loading on curing Characteristics and physical Properties of Ternary Rubber Blend Composites

This study investigates the effect of carbon black (CB) filler loading on the mechanical and rheological properties of natural rubber (NR) / styrene-butadiene rubber (SBR)/ acrylonitrile-butadiene rubber (NBR) ternary rubber composites. Physico-mechanical properties such as tensile strength, modulus, stress, elongation at break , tear strength, compression stress, and crosslink density were studied. more...
