POLYAMIDE RESIN COMPOSITION AND INJECTION MOLDED PRODUCT THEREFROM

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin composition giving molded products that have excellent appearance and high strength and rigidity and can obtain molded products having uniform hollow part length and the hollow thickness by the gas-assist injection molding. SOLUTION: This polyamide resin composition comprises (A) 30-70 pts.wt. of (A) a polyamide composition including (al) 50-100 wt.% of half-aromatic polyamide constituted with 70-95 wt.% of hexamethylene adipamide units from adipic acid and hexamethylenediamine, and 5-30 wt.% of hexamethylene isophthalamide units from isophthalic acid and hexamethylenediamine and (a2) 0-50 wt.% of aliphatic polyamide where the crystallization temperature is <=210 deg.C, 10-60 pts.wt. of (B) glass fiber with an average fiber diameter of 15-30μm and 10-60 pts.wt. of (C) inorganic fillers other than glass fibers.
