Application
ANTIOXIDANT HONOX-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. It can be used
with benzotriazoles or HALS for thermal and light stabilization in outdoor use. It
exhibits a synergistic effect when it is used in combination with thioester
antioxidants. info at hhochem.com
