介绍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.
