<P>PROBLEM TO BE SOLVED: To provide a polyamide resin composition having high vibration welding strength. <P>SOLUTION: The polyamide resin composition is obtained by blending, based on 100 pts.wt. of a polyamide having a melting point of ≤275°C, 20-70 pts.wt. of an inorganic filler and 0.02-0.3 pt.wt. of a phosphorus-containing compound in which the oxidation number of phosphorus is ≤4. Preferred as the phosphorus-containing compound is sodium hypophosphite. The obtained polyamide resin composition is suitable for vibration welding, spin welding and ultrasonic welding. <P>COPYRIGHT: (C)2009,JPO&INPIT |
