PURPOSE: To provide a thermoplastic elastomer applicable to a coatingless type air bag covering material which needs to have the freedom of color matching, moldability, heat resistance, light discoloration resistance, scratch resistance, and low-temperature impact resistance. CONSTITUTION: A thermoplastic elastomer is produced by dynamically melt- kneading a resin composition comprising an ethylene/α-olefin/nonconjugated diene copolymer rubber, a polypropylene resin, an organosiloxane crosslinking agent having at least two SiH groups in the molecule and a hydrosilylation catalyst, adding a styrene elastomer component to the mixture, and further kneading the resulting mixture. |
