Polyamide resin composition for blow molded products in contact with high pressure hydrogen and blow molded products using the same

摘要

A polyamide resin composition that has excellent blow moldability and retention stability, can suppress the local increase in residual deformation of the molded product, and can obtain a blow molded product in which the occurrence of defects is suppressed even when charging and discharging high pressure hydrogen are repeated. It aims to provide. To this end, polyamide 6 resin (A) 70 to 99 parts by weight and impact-resistant material (B) 1 to 30 parts by weight total 100 parts by weight, metal halide (C) 0.005 to 1 parts by weight of polyamide A resin composition, wherein the polyamide resin composition has a melt tension of 20 mN or more when measured at 260°C, and a pullout speed at break of 50 m/min or more when measured at 260°C. It provides a polyamide resin composition for blow-molded articles in contact with.
