VEENOX 168 PW

Veenox 168 PW is a hydrolytically stable phosphite processing stabilizer. Veenox 168 PW reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants. Veenox 168 PW is an Organophosphite Antioxidant of low volatility and is particularly resistant to hydrolysis. It protects polymers which are prone to oxidation during the processing (comounding/palletizing,fabrication and recycling) from molecular weight change (by Chain scission or crosslinking) and prevents discolouration. Veenox 168 PW performs best when combined with Veenox 1010 PW and gives storage stability and long term heat stability against thermal and oxidative degradation.
