ULTRANOX™ 626 Antioxidant For Food Packaging

What is ULTRANOX™ 626?


 
ULTRANOX™ 626 is a high-performance organophosphite antioxidant that is specially designed for demanding applications where color stability is required. ULTRANOX™ 626 is a secondary antioxidant with one of the market's highest phosphorous content, providing improved protection, reduced loading rate, and lower overall cost.It is one of the highest phosphorous content secondary antioxidants in the market, which provides improved protection, reduced loading rate, and lower overall cost. This phosphite antioxidant is available in powder and granular form and supplied by SI Group, a lead in polymer additives and stabilizers. 

ULTRANOX™ 626 is also featured with FDA food contact approval for conditions A through H for use in polypropylene (PP) polymers and copolymers. The FDA approval, combined with performance benefits make ULTRANOX® 626 ideal for use in a wide range of polypropylene packaging and many other food contact applications.
