Patent ID: 6913043

Claim:
A composition comprising by weight: 70 to 88% of at least one polyamide chosen from PA-11, PA-12, aliphatic polyamides resulting from the condensation of an aliphatic diamine having from 6 to 12 carbon atoms and an aliphatic diacid having from 9 to 12 carbon atoms, and 11/12 copolyamides having either more than 90% of nylon-11 units or more than 90% of nylon-12 units, wherein the polyamide contains a catalyst chosen from phosphoric acid and hypophosphoric acid; 4 to 10% of a plasticizer; between 8 and 22% of a nitrile butadiene rubber elastomer or a hydrogenated nitrile butadiene rubber elastomer; and the sum of the amount of plasticizer and the amount of elastomer is between 12 and 30%.
