POLYAMIDE RESIN COMPOSITION FOR MOLDED ARTICLE TO BE IN CONTACT WITH HIGH-PRESSURE HYDROGEN, AND MOLDED ARTICLE OBTAINED THEREFROM

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 temp...

Beschreibung
Zusammenfassung:	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) being in an amount of 0.01 to 5 parts by weight based on 100 parts by weight of the polyamide 6 resin (A). Provided is a polyamide resin composition that can provide a molded article having excellent weld properties and less likely to suffer failure points despite repeated charging and discharging of high-pressure hydrogen.
