A thermoplastic composition suitable for molding on a closure cap to form a gasket. The composition includes: a) a thermoplastic polymer, chosen among: polypropylene, polyethylene, polyethylene-polypropylene elastomer copolymer, ethylene vinyl acetate, polyethylene-polypropylene alloys, styrene-butadiene-styrene copolymers, ethylene-propylene-diene terpolymers, and a coterpolymer of ethylene; and b) a two-phase blend in which one phase is based on polypropylene and the other phase is based on an ethylene propylene copolymer, these two phases being arranged to form a co-continuous fabric. |
