ULTRANOX™ 627AV
ULTRANOX™ 627AV 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. Similar to ULTRANOX™ 626 but in a free-flowing form with an inorganic neutralizer for improved handling characteristics.
ULTRANOX™ 627A 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™ 627A synergizes with benzophenone and benzotriazole light stabilizers.
