Technical product information

Features and Benefits

Irgafos 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 from the Irganox range. • Can be used in combination with light stabilizers from the Tinuvin and Chimasorb range.

Applications

Irgafos 126 provides outstanding processing stability in a variety of applications and substrates, including polyethylene, polypropylene and ethylenevinylacetate copolymers. Irgafos 126 can also be used in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives and other organic substrates. Irgafos 126 is particularly effective when used in combination with primary antioxidants of the Irganox range.

Use Guidelines

In the recommended applications, the concentration levels for Irgafos 126 range typically between 0.05 % and 0.15 % depending on substrate and processing conditions. The optimum level is application specific. Performance data of Irgafos 126 in various organic polymers and applications are available upon request.
