Veenox **8 PW is a hydrolytically stable phosphite processing stabilizer. Veenox **8 PW
reacts during processing with hydroperoxides formed by autoxidation of polymers
preventing process induced degradation and extending the performance of primary
antioxidants.
Veenox **8 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 **8 PW
performs best when combined with Veenox ***0 PW and gives storage stability and long
term heat stability against thermal and oxidative degradation.
