Abstract: A polyamide resin composition for an extrusion-molded article exposed to high-pressure hydrogen gas contains: 70 to 99 parts by weight of a polyamide 6 resin (A); 1 to 30 parts by weight of an impact modifier (B); and 0.005 to 1 parts by weight of a metal halide (C) with respect to a total of 100 parts by weight of the polyamide 6 resin (A) and the impact modifier (B). The polyamide resin composition has a melt tension of 20 mN or more when measured at 260° C. and a take-up speed at strand break of 30 m/min or more when measured at 260° C.

Abstract: A polyamide resin composition for a molded article exposed to high-pressure hydrogen contains a polyamide 6 resin (A) and a polyamide resin (B) having a melting point, as determined by DSC, that is not higher than a melting point of the polyamide 6 resin (A) +20° C. and a cooling crystallization temperature, as determined by DSC, that is higher than a cooling crystallization temperature of the polyamide 6 resin (A), the polyamide resin (B) present in an amount of 0.01 to 5 parts by weight based on 100 parts by weight of the polyamide 6 resin (A). The polyamide resin composition can provide a molded article having excellent weld properties and is less likely to suffer failure points despite repeated charging and discharging of high-pressure hydrogen.

Abstract: A polyamide resin composition for a molded article exposed to high-pressure hydrogen contains a polyamide resin (A) including a unit derived from hexamethylenediamine and a unit derived from an aliphatic dicarboxylic acid of 8 to 12 carbon atoms and an ethylene/α-olefin copolymer (B) modified with an unsaturated carboxylic acid and/or a derivative thereof. The polyamide resin composition provides a molded article having excellent flexibility and heat cycle resistance and less likely to suffer failure points despite repeated charging and discharging of high-pressure hydrogen.
