Polyamide resin composition for foamed molded article and polyamide resin foam molded article comprising the same

摘要

The present invention relates to a crystalline polyamide resin composition comprising a crystalline polyamide resin (A), a carbon black (B) having no crystallization promoting action on the crystalline polyamide resin, and an inorganic reinforcing material (C) (A) and (B) is from 60 to 90% by mass and (C) is from 10 to 40% by mass, provided that the total of (A) and (C) is 100% by mass , And the melting point and the crystallization temperature of the polyamide resin composition have a specific relationship. The above-mentioned polyamide resin composition can provide a polyamide foamed molded article that is lightweight and has high load carrying capacity and a good molding appearance.
