Application
ANTIOXIDANT 245 is a partially- hindered phenolic antioxidant that provides excellent processing and long term thermal stability. It is mainly used in the processing and improvement of long-term thermal stability of styrene polymer such as HIPS, MBS and ABS, engineering plastic such as POM, PA and polyurethane . It is also an effective chain terminator in PVC polymerizations. It can be added into monomers before polymerization when it is used for HIPS and PVC.
