<P>PROBLEM TO BE SOLVED: To provide a polyphenylene sulfide resin extrusion-molded article having excellent surface appearance without decreasing characteristics of superior heat resistance, chemical resistance, wear resistance and electric insulating property, which are inherent to a polyphenylene sulfide resin. <P>SOLUTION: The polyphenylene sulfide resin extrusion-molded article is obtained, which contains as a principal component a polyphenylene sulfide resin showing a melt flow rate (measured in accordance with ASTM D-1238-70 at a temperature of 315.5°C and under a load of 5,000 g) of 30 g/10 min or less and a crystallization time at 220°C of 3.0 minutes or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
