POLYACETAL RESIN COMPOSITION |
摘要 |
PURPOSE:To obtain a polyacetal resin composition, capable of suppressing the deterioration and discoloration of a resin and bleeding and discoloration of an additive as much as possible in exposure to light for a long period, capable of retaining the initial surface conditions of moldings and excellent in weather and environmental resistance. CONSTITUTION:This polyacetal resin composition is obtained by adding and blending (B) 0.01-2.0 pts.wt. ultraviolet ray absorber and (C) (C-1) 0.01-1 pt.wt. low-molecular weight hindered amine-based substance having <700 molecular weight and (C-2) 0.01-4 pts.wt. high-molecular weight hindered amine-based substance having >=700 molecular weight with (A) 100 pts.wt. polyacetal resin. |
