4,4'-Isopropylidenediphenol C12-14 alcohol phosphite
A polymeric phosphite antioxidant with high molecular weight and high phosphorus content is mainly used to partially replace organotin stabilizers in non-toxic products such as PVC materials, films, and sheets. It can also be used as an oxygen heat stabilizer in PE, PP, ABS, and SBS, and as a secondary antioxidant, it has a strong ability to decompose hydroperoxides. It has a good synergistic effect with main antioxidants such as "1010", which can improve the antioxidant effect and reduce product costs. It can be used in polymer materials such as PVC and polyurethane after compounding with hindered phenolic antioxidants.
Suggested addition amount: 0.1-2.0%.
