Doverphos® S-9228T

Doverphos® S-9228T by Dover Chemical (ICC Industries) is bis (2,4-dicumylphenyl) pentaerythritol diphosphite with 1% triisopropanol amine. It is free-flowing solid phosphite antioxidant. It offers hydrolytic stability and outstanding performance in stabilizing polymers against melt flow degradation & color change. Doverphos® S-9228T in polymer systems has improved permanence where other phosphites may lose activity even when encapsulated in the polymer or in one-pack blends. It does not hydrolyze and cause black specks as do other phosphites.
