Document Type and Number:
Japanese Patent JP2017137386
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyacetal resin composition which has excellent impact resistance and is capable of sufficiently suppressing contamination of a mold and generation of formaldehyde, and a resin molded article obtained by using the same.SOLUTION: In the polyacetal resin composition, 1-120 pts.mass of a thermoplastic polyurethane (B) and 0.01-5 pts.mass of a formaldehyde scavenger (C) are blended based on 100 pts.mass of a polyacetal resin (A). The formaldehyde scavenger (C) comprises at least one selected from the group consisting of specific dihydrazone compounds (C1) and hydrazide compounds (C2). The thermoplastic polyurethane (B) has a residual isocyanate content of 0.10 mass% or less and a water content of 3,000 mass ppm or less and exhibits a melt viscosity of 200,000 poise or more at 180°C.SELECTED DRAWING: None
