Abstract

La presente invención se refiere a una composición para moldeo de nylon, caracterizada porque comprende una resina básica de nylon y un sistema de estabilización, el cual incluye: i) un antioxidante fenólico obstruído o impedido, ii) un compuesto de fosfito, iii) un estabilizador de la luz, de amina obstruída, y opcionalmente, iv) un absorbente de la luz UV de benzotriazol este sistema de estabilización está presnte en la composición en una cantidad suficiente para lograr una diferencia de color, según se calcula en unidades CIELab bajo el iluminante "D-65", de acuerdo con la Norma D-2244 de ASTM, de menos de aproximadamente 1.5, cuando se expone a una irradiación de 601.6 kJ/m2, en un medidor ambiental de arco Xenon, operado de acuerdo con la norma J1885 de la SAE y que exhibe al menos 75 por ciento de retención superficial de brillo, aproximadamente, despues de la irradiación.
