Fa'atatauga
O le Antixoidant 245 o se ituaiga o antioxidant phenolic asymmetric maualuga, ma o ona uiga faʻapitoa e aofia ai le maualuga o le antioxidation, le maualalo o le volatility, teteʻe atu i le faʻamaʻiina o le oxidation, le taua o le synergistic faʻatasi ma le antioxidant fesoasoani (e pei o le monothioester ma le phosphite ester), ma le tuʻuina atu o oloa i le faʻaleleia o le tau pe a faʻaaogaina ma faʻamalama malamalama. 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 e pei o POM ma PA, ae o loʻo avea foʻi ma faʻauʻuga o filifili i le PVC polymerization. E le gata i lea, o le oloa e leai sona aafiaga i polymer reactions. A faʻaaogaina mo HIPS ma PVC, e mafai ona faʻaopopo i monomers aʻo leʻi faia le polymerization.
