摘要： 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.
