Patent ID: 7045185

Claim:
A composition comprising by weight: 70 to 87% 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 does not contain a catalyst chosen from phosphoric acid and hypophosphoric acid; 5 and 9% of a plasticizer; 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 13 and 30%.
