Product Description

Antioxidant 168 CAS 31570-04-4

Antioxidant 168 is an organophosphate of low volatility and is particularly resistant to hydrolysis. It protects polymers which
are prone to oxidation, during the processing steps (compounding/ pelletizing, fabrication and recycling) from molecular weight
change (e.g. chain scission/crosslinking) and prevents discoloration.

Antioxidant 168 performs best when combined with other antioxidants. Blends of antioxidant 168 with the antioxidant range
(Antioxidant B-blends) and with Hydroxylamine FS042 are particularly effective.
