POLYAMIDE RESIN COMPOSITION AND HOLLOW MOLDED BODY CONTAINING SAME

摘要

Provided are: a composition having favorable molding characteristics and working characteristics when producing a molded body and having a flexibility, burst pressure resistance, cold shock resistance, environmental resistance, and chemical resistance at least equivalent to PA12; and a hollow molded body using the composition. A polyamide resin composition containing PA6/12 (component A), a plasticizer (component B) and a modified polyolefin (component C) is characterized by: component A containing a unit (a) derived from epsilon-aminocaproic acid or epsilon-caprolactam and a unit (b) derived from omega-laurolactam or aminododecanoic acid; unit (a) being 60-98 wt% and unit (b) being 40-2 wt% of the constituent units of component A; and the amount contained of component A being 50-98 wt%, the amount contained of component B being 20-1 wt%, and the amount contained of component C being 30-1 wt% of the polyamide resin composition.
