Antioxidant 626 is a white to off-white powdery substance with low volatility and higher efficiency. It is often used in combination with hindered phenolic antioxidants.
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. It is so effective that it can replace another phosphite antioxidant in your formula and deliver equivalent performance at a significantly lower dosing rate.Basic Info-
