Irgafos® 168

Irgafos® 168 by BASF is tris(2,4-di-tert.-butylphenyl) phosphite. It is a hydrolytically stable phosphite processing stabilizer. It also acts as a secondary antioxidant which induces degradation and extends the performance of primary antioxidants. It has low volatility and is particularly resistant to hydrolysis. Provides storage stability and gives the polymer long term protection against thermo-oxidative degradation, during the processing steps (compounding/pelletizing, fabrication and recycling) from molecular weight change (by chain scission or crosslinking) and prevents discoloration. Irgafos® 168 is suitable for polyesters, styrene homo- and copolymers, polyolefins, olefin-copolymers, HDPE & LLDPE, polypropylene, polybutene and ethylene vinyl acetate copolymers applications. It is also used in polycarbonates, polyamides, elastomers such as BR, SEBS, SBS, and other organic substrates.
