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.

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 translation: 用于暴露于高压氢的模塑制品的聚酰胺树脂组合物含有聚酰胺6树脂（A）和聚酰胺树脂（B），其通过DSC测定的熔点不高于聚酰胺的熔点 6树脂（A）+ 20℃，通过DSC测定的冷却结晶温度高于聚酰胺6树脂（A）的冷却结晶温度，聚酰胺树脂（B）的存在量为0.01 至5重量份，基于100重量份的聚酰胺6树脂（A）。 聚酰胺树脂组合物可以提供具有优异的焊接性能的模制品，并且尽管反复充放电高压氢，也不太可能遭受故障点。
