PURPOSE: A polyoxymethylene resin composition and a speaker grill for wheels containing the composition are provided, wherein the composition shows favorable weather resistance, gloss, melt index and tensile strength to the preparation of a speaker grill for wheels. CONSTITUTION: The polyoxymethylene resin composition comprises 100 parts by weight of a polyoxymethylene resin; 0.01-5 parts by weight of a triazine-based or hindered amine-based photostabilizer; 0.1-5 parts by weight of a polyether-ester block copolymer; 1-5 parts by weight of an inorganic filler having a particle size of 5 micrometers or less; and 0.1-3 parts by weight of sorbitan fatty acid ester. The resin composition has a melt index of 30-60 g/10 min, a tensile strength of 600 kg/cm2 and a surface gloss of 20 or less (by JIS K7105 method). |
