Antioxidant SF-626

Characterization： SF-626 is a high performance phosphite processing stabilizer. Which protects polymers from thermo-oxidative degradation during processing and extending the performance of primary antioxidants.

Chemical Name: Bis-(2 ,4-di-tert-butyl phenyl ) Pentaerythritol Diphosphite

Molecular Weight: 604 Molecular formula: C32H50O6P2

Structure:

Features/Benefits: SF-626 is a high performance phosphite processing stabilizer. Which is high performance with low concentration levels. Can be used in combination with primary antioxidants and other additives.

Applications: SF-168 can be used in polyethylene, polypropylene and ethylenevinylacetate copolymers. Also be used in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives and other organic substrates. Recommended dosage is between 0.05 % and 0.15 % depending on substrate and processing conditions.
