The cushion gum may comprise between 10 and 30 phr of the resin in particular embodiments. The plasticizing resin may be a terpene resin comprising units resulting from the polymerization of limonene, alpha pinene, beta pinene or combinations thereof; homopolymers or copolymers of cyclopentadiene (CPD) or dicyclopentadiene (DCPD), homopolymers or copolymers of terpene, homopolymers or copolymers of a C 5 cut and mixtures thereof; and/or copolymers of (D)CPD/ vinyl-aromatic, of (D)CPD/ terpene, of (D)CPD/ C 5 cut, of teipene/vinyl-aromatic, of C 5 cut/vinyl-aromatic and of combinations thereof.",
