Patent ID: 7744781

Claim:
A conductive thermoplastic elastomer composition comprising: a component (A) comprising a thermoplastic elastomer composition containing a mixture of an olefin resin and a styrene thermoplastic elastomer and at least one rubber component selected from the group consisting of EPDM and NBR dynamically crosslinked and dispersed in the mixture of the olefin resin and the styrene thermoplastic elastomer; a component (B) comprising an ionic-conductive agent containing an ethylene oxide-propylene oxide-allyl glycidyl ether copolymer and a metal salt, composed of metal cations and anions having a fluoro group and a sulfonyl group, contained in said ethylene oxide-propylene oxide-allyl glycidyl ether copolymer; and a component (C) comprising an ethylene-acrylic ester-maleic anhydride copolymer; wherein a mixing ratio between the olefin resin and the styrene thermoplastic elastomer of the component (A) is 30 to 50 parts by mass of the olefin resin mixed with 100 parts by mass of the styrene thermoplastic elastomer; wherein 200 to 400 parts by mass of the at least one rubber component is mixed with 100 parts by mass of the mixture of the olefin resin and the styrene thermoplastic elastomer; and wherein the conductive elastomer composition contains 20 to 40% of the component (B) in a volume fraction.
