Applications:
Omnistab AN 245 is a sterically hindered phenolic antioxidant particularly suitable for organic substrates. It protects the substrates against thermo-oxidative degradation during manufacturing, processing and end-use. Omnistab AN 245 is mainly used in styrene polymers such as impact modified PS, ABS, MBS, SB and SBR latices as well as in POM. It is also very useful for polyurethane, polyamides, polyesters, PVC and other engineering plastics and adhesives.

Features / Benefits:
Omnistab AN 245 is very effective as a chain stopper during PVC polymerization.
Omnistab AN 245 provides significant advantages such as maintenance of original melt flow, low colour formation, improvement of long-term thermal stability and stabilization of polymers during processing.
