PROBLEM TO BE SOLVED: To provide a polyacetal resin composition which has excellent properties such as high rigidity, low warpage and low deformation, has improved mechanical strength, and also has greatly improved properties such as rupture life (creep property) under dipping in hot water or constant stress. SOLUTION: The polyacetal resin composition comprises (A1) 30-95% by weight of a polyacetal resin having a linear molecular structure, (A2) 0.05-10% by weight of a polyacetal resin having a branched or cross-linked structure, (B) 5-50% by weight of a powder and granular glass-based inorganic filler, (C) 0.1-10% by weight of a trifunctional isocyanate compound, (D) 0.05-2% by weight of a compound selected from an amine-based compound (D1) and an organometallic compound (D2) containing a metal selected from Sn, Zn and Pb, and (E) 0-20% by weight of any additive. The polyacetal resin composition has a total weight of 100% by weight. COPYRIGHT: (C)2010,JPO&INPIT |
