Specification

Applications
Antioxidant 126 provides outstanding processing stability in a variety of applications and substrates, including polyethylene, polypropylene and ethylene-vinylacetate copolymers.
Antioxidant 126 can also be used in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives and other organic substrates. Antioxidant 126 is particularly effective when used in combination with HP136, a high performance lactone based melt processing stabilizer, and primary antioxidants range.
Antioxidant 126 is a high performance solid organo-phosphite which protects polymers from degradation during the processing steps (compounding, pelletizing, fabrication, recycling).
● Protects polymers from molecular weight changes (e.g. Chain scission or crosslinking)
● Prevents polymer discoloration due to degradation
● High performance at low concentration levels
● Synergistic performance when used in combination with primary antioxidants
● Can be used in combination with light stabilizers from the UV range
