DOVERPHOS® S-9228T

通用系列： Additive -- Antioxidant / Heat Stabilizer -- Phosphite • 提供方： Dover Chemical Corporation

Doverphos S-9228T is Doverphos S-9228 with 1% triisopropanol amine.

Doverphos S-9228T is a free flowing solid phosphite antioxidant. This product has outstanding hydrolytic stability and outstanding performance in stabilizing polymers against melt flow degradationand color change.

Key Benefits

Doverphos S-9228T does not hydrolyze upon exposure to moisture in the environment. Phosphite does not have to be thrown away if packaging is accidentally left open.

Since Doverphos S-9228T is hydrolysis resistant, special packaging is not required, which may be difficult to dispose.

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.

Doverphos S-9228T does not hydrolyze and cause black specks as do other phosphites. These black specks, which cause visual defects in polymer, can plug filter packs in extrusion systems.

Acid degradation products resulting from hydrolysis of the phosphite can react with other additives in the polymer, reducing their effectiveness.
