POLYAMIDE RESIN COMPOSITION

摘要

[Problems] Provided is a polyamide resin material having high elastic modulus, good gas barrier properties, low water absorption and excellent flexibility. [Means for solving the problems] This is a polyamide resin composition comprising a polyamide resin (A) composed of a diamine structural unit and a dicarboxylic acid structural unit wherein 70 mol % or more of the diamine structural unit is derived from xylylenediamine and 50 mol % or more of the dicarboxylic acid structural unit is derived from sebacic acid, and 1 to 40 parts by mass of at least one copolyamide (B) selected from the following group consisting of (B-1)-(B-3) per 100 parts by mass of the polyamide resin (A);
(B-1): a copolyamide 6/66/12;
(B-2): a copolyamide 6/66/11;
(B-3): a polyether-polyamide copolymer composed of a polyamide 12 unit or a polyamide 11 unit and a polyether unit.
