<P>PROBLEM TO BE SOLVED: To provide a polyacetal resin composition in which, while maintaining the various characteristics of a polyacetal resin blended with calcium carbonate, a molding shrinkage ratio is further reduced even without increasing the blending amount of calcium carbonate, and simultaneously, high mechanical properties and the suppression of bleed out can be achieved. <P>SOLUTION: The resin composition includes: (A) a polyacetal resin of 100 pts.mass; (B) calcium carbonate; (C) saturated fatty acid of ≤3 pts.mass; and (D) a non-polymer reactive nitrogen compound of ≥0.05 pt.mass; wherein the content ratio of the saturated fatty acid (C) to the non-polymer reactive nitrogen compound (D) is 8 to 30 based on mass. <P>COPYRIGHT: (C)2013,JPO&INPIT |
