POLYAMIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a polyamide resin composition, having excellent rigidity and toughness together and especially excellent in high-speed planar impact fracture characteristics and having balanced and excellent characteristics of molded product surface appearance and dimensional stability. SOLUTION: This polyamide resin composition is obtained by melt kneading 100 pts.wt. of a polyamide resin with 5-150 pts.wt. of a nonfibrous inorganic filler having 0.05-10μm average particle diameter and/or a fibrous inorganic filler having 0.05-10μm average fiber diameter except glass fibers. The resultant composition has >=4 g/m<2> of the polyamide component sticking to the inorganic filler based on a unit surface area measured by a BET method when dissolving the composition in hexafluoroisopropanol and recovering the inorganic filler.
