What Is Antioxidant 168?
Antioxidant 168 is a phosphite secondary antioxidant used to decompose hydroperoxides during polymer processing. It can be evaluated alongside a primary hindered-phenol antioxidant. The supplied grade controls purity, melting range, volatile matter, acid value and residual 2,4-di-tert-butylphenol. Light-transmittance values require an agreed sample-preparation method. Keep dry and assess processing and color stability in the complete formulation.
The ≥99% grade is supplied as white crystalline powder. The specification table, TDS and SDS on this page cover the main purchasing parameters. For a quotation, send the application, quantity and destination.
