Fa'aaogāga
Antixoidant 245 o se ituaiga maualuga-lelei asymmetric phenolic antioxidant, ma o ona vaega faapitoa e aofia ai le maualuga maualuga antioxidation, volatility maualalo, tetee atu i oxidation lanu, aafiaga synergistic taua ma fesoasoani antioxidant (e pei o le monothioester ma le phosphite ester), ma tuuina atu oloa weathering lelei. tete'e pe a fa'aogaina ma fa'amautu mama.O le Antioxidant 245 e masani ona faʻaaogaina e fai ma faʻagasologa ma taimi umi mo le styrene polymer e pei o HIPS, ABS, MBS, ma faʻainisinia thermoplastics pei o le POM ma le PA, ae o loʻo avea foʻi ma faʻauʻuga o filifili i le polymerization PVC.E le gata i lea, o le oloa e leai sona aafiaga i luga o polymer reactions.Pe a faʻaaogaina mo HIPS ma PVC, e mafai ona faʻaopopo i monomers aʻo leʻi faia le polymerization.
