Abstract: A heavy truck tire tread that includes a series of at least 50 similar tread features repeated along its longitudinal direction that include two ducts extending from the surface in the thickness direction, the ducts being joined together by one sipe. They further have one void in fluid communication with the two ducts, the void extending substantially parallel to the tread surface and having a void section area of at least 10 mm2. The tread is formed at least in part of a rubber composition comprising at least 75 phr of a first rubber component selected from a polybutadiene rubber (BR), a styrene-butadiene rubber (SBR) or combinations thereof having a Tg of between −80° C. and −110° C. The rubber composition may further include at least 40 phr of a plasticizing resin having a Tg of at least 25° C. and a reinforcing filler.

Abstract: The subject matter of the present invention relates to rubber mix having improved wear resistance comprised of carbonate functionalized elastomer and a reduced graphene oxide filler. The resulting rubber has comparable wear resistance and better rigidity versus energy dissipation compromise as compared to rubber mixes having non-functionalized elastomer and reduced graphene oxide reinforcement.

Abstract: An improved rubber composition and method to create the improved rubber composition is achieved by milling reduced graphene oxide (“RGO”) in liquid rubber to induce a reduction of bulk density of the reduced graphene oxide while maintaining dispersibility in rubber without using a solvent-based process resulting in an industrially scalable process and an improved rubber composition.
