Abstract: The disclosure relates to a lubricating composition consisting essentially of a decarboxylated rosin acid (DCR), a base oil, and optional additives, and methods for using same. The decarboxylated rosin acid has a density of 0.9 to 1.0 g/cm3 at 20° C., a viscosity of 15 to 60 cSt at 40° C., and an acid value of <50 mg KOH/g. The lubricating compositions containing the DCR is characterized as having improved anti-wear and friction reducing properties, as well as improved electrical properties, and cooling performance for use in electric and hybrid vehicles. In embodiments, the lubricating composition exhibits a wear scar diameter of <350 ?m, according to ASTM D6079.

Abstract: A tire composition is disclosed. The composition comprises a rubber component and based on 100 parts by weight (phr) of the rubber component, 50-200 phr of covered silica, with the covered silica comprising silica core and a first resin covering the silica core, wherein the first resin is not chemically bonded to the silica core. The silica core is covered with the first resin by mixing a slurry comprising silica core with a mixture containing the first resin as a solution, an aqueous dispersion; or a solution by dissolving the first resin in a solvent.

Abstract: The disclosure relates to elastomeric compositions having improved soft touch feel to skin, and in particular grip, especially during wet/humid conditions. In one embodiment, the compositions are part of a composite system, wherein the compositions are connected, for example bonded, molded, over-molded or co-extruded to a substrate, such as a thermoplastic, wood, glass or metal. The elastomeric composition comprises: (a) one or more copolymers present in an amount of 10 wt. % to 90 wt. %, selected from styrenic block copolymers and isoprene polymers; (b) one or more resins an amount of 2 wt. % to 20 wt. %; and optionally (c) at least one softener, filler, antioxidant or the like present in an amount up to 80 wt. %. The resin is selected from coumarone-indene resin, petroleum hydrocarbon resin, terpene based polymers, styrene-alpha-methyl-styrene resins, rosin derived resins, and mixtures thereof.
