ULTRANOX™ 626
ULTRANOX™ 626 is a high performance solid phosphite antioxidant that improves color stability and reduces polymer degradation during compounding, fabrication, and end use in a variety of resins.
ULTRANOX™ 626 is a solid organophosphite antioxidant that improves gas fading performance and color stability during compounding, fabrication, and end use. It delivers high performance at low loading rates, making this a cost effective addition to polymer formulas. ULTRANOX™ 626 synergizes with benzophenone and benzotriazole light stabilizers.
ULTRANOX™ 626 is so effective, it can replace another phosphite antioxidant in your formula and deliver equivalent performance at a significantly lower dosing rate. We've provided a handy calculator below to help you determine the dose of ULTRANOX™ 626 needed to replace your current phosphite antioxidant.
