Dover Chemical DOVERPHOS S9228® Solid Phosphite Antioxidant
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: Doverphos S-9228® is a free flowing solid phosphite antioxidant developed by 1057. Doverphos S-9228® has excellent hydrolytic stability without the addition of inert products or triisopropanol amine. Doverphos S-9228® exhibits similar color performance as demonstrated by distearyl pentaerythritol diphosphite – Doverphos S-680 and other similar pentaerythritol diphosphites. Because of its high melting point, Doverphos S-9228® can be utilized in applications that require processing at elevated temperatures.
