Influence of particle size on inhomogeneity in rubber compositions of NR/BR blend wear particles by single particle analysis

Abstract

Tire wear particle has been considered as one of environmental pollution sources and its sizes are widely ranged from PM 2.5 to several hundred micrometer (μm). A bus tire tread is generally composed of NR and BR. In the present work, difference in the rubber compositions of wear particles of a model bus tire tread compound (NR/BR = 80/20) depending

Shades of grey—tire characteristics and road surface influence tire and road wear particle (TRWP) abundance and physicochemical properties

“…In contrast, the firm-elastic TRWP collections both had elevated relative fractions of PIP compared to their parent tires, to the extent that, in the studless tire TRWP, PIP had become the dominant measured polymer, while in the summer tire TRWP, PIP was measured at a higher concentration than that of the parent tread (Figure 2C). A related finding was reported by Chae and Choi (2022), who measured elevated PBD concentrations in a proportion of smaller (<212 µm mesh fraction) wear particles, compared to the original rubber blend, in this case, a PBD phase dispersed in a PIP matrix. They attributed these results to inhomogeneity of the blended rubber phases.…”
