Abstract

See full text

A shoe sole comprising an elastomeric composition comprising: (D) 100 phr of a mixture of rubbers comprising: i. from 40 to 70% by weight of an isoprene polymer; ii. from 20 to 50% by weight of polybutadiene; iii. from 10 to 40% by weight of an SBR having a glass transition temperature (Tg) from −60 to −40° C.; (E) from 50 to 100 phr of amorphous carbon black having a surface area greater than 85 m2/g measured with the ASTM D6556 method, and a dibutyl phthalate absorption index (DBPA) greater than 90 measured with the ASTM D2414 method; (F) from 1 to 30 phr of graphene nano-platelets, wherein at least 90% of said graphene nano-platelets has a side dimension (x, y) from 50 to 50000 nm and a thickness (z) of 0.34 to 50 nm, and wherein said graphene nano-platelets have a C/O ratio ≥100:1.
