      Applications: This product is one of the few kinds of antioxidant, which is non-toxic, tasteless, light colored. Widely apply in each kind of elastomer. It can be used in polyethylene, polypropylene, polyvinyl chloride and other plastic masterbatch. It may use as the urethane foam as well as the electric wire, the electric cable, packaging material for food, the adhesive antioxidant, especially for heat-resisting, lightfastness, ageing resistance in the neoprene colored cable sheath, antioxidant KY-405 is are remarkable. It can use as lightfastness and ageing resistance antioxidant in the polyether and foam, and also as lubricant antioxidant. It's especially effective to protect neoprene, polyacrylate rubber, polyether polyol and so on from ageing resistance because of high fever, light and some other factors. It has good cooperative effect with the sulf-antioxidant. Storage:  Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
