CONDUCTIVE POLYAMIDE RESIN COMPOSITION AND MOULDED ARTICLE PRODUCED FROM THE COMPOSITION

摘要

PURPOSE: Provided are a conductive polyamide resin composition excellent in conductivity, impact resistance, and flexibility which are required for automobile components of fuel system, and flexibility which is advantageous to moulding, and a moulded article produced from the composition. CONSTITUTION: The conductive polyamide resin composition comprises (a) 40-70 wt% of semi-crystalline polyamide resin; (b) 15-40 wt% of thermoplastic elastomer grafted with 0.5-2.0 % of maleic anhydride; (c) 9-20 wt% of carbon black powder; (d) 1-10 wt% of sulfonamide based material of formula 1: R1-SO2-NH-R2(wherein R1 and R2 represent one selected from alkyl, benzyl, phenyl, alkylphenyl and dialkylphenyl, and the alkyl is CnH2n+1(n<=8)); and (e) 0.001-0.02 wt% of dicarboxylic material of formula 2: HOOC(CH2)n-COOH.
