    摘要: A polyoxymethylene molding composition which exhibits improved ambient and heat aged color stability includes a metal deactivator and calcium hydroxystearate. One preferred composition of the invention includes: (a) greater than about 95 weight percent of polyoxymethylene, (b) between about 0.01 to about 0.1 weight percent of 3 salicyloyl-amido-1,2,4 triazole or tris-2-tert.butyl- 4-thio-(2'methyl-4'hydroxy-5'tert.butyl) phenyl-5-methyl phenyl phosphite, (c) between about 0.015 to about 0.4 weight percent of 2,4,6-triamino-sym-triazine, (d) between about 0.25 to about 1.0 weight percent of tetrakis(methylene-(3,5-di-tert-butyl- 4-hydroxyhydrocinnamate)) methane, (e) between about 0.05 to about 0.2 weight percent of calcium 12-hydroxystearate, and (f) between about 0.1 to about 0.3 weight percent of N-N'-ethylenebisstearamide. Due to their enhanced color stability, the compositions of this invention find particular utility as molded automobile components.
