1. A composition comprising:
a plurality of elastomeric particulates comprising a polyurethane polymer and a plurality of nanoparticles, the polyurethane polymer defining a core and an outer surface of the elastomeric particulates and the plurality of nanoparticles being associated with the outer surface;
wherein the elastomeric particulates have a D50 ranging from about 1 μm to about 130 μm with a size span of about 0.9 or less.
