Dragonox®-5057 is used in combnation with hindered phenols, such as Dragonox®-1135, as an excellent co-stabilizer in polyurethane foams. In the manufacture of flexible polyurethane slabstock foams, core discoloration or scorching results from the exothermic reaction of diisocyanate with polyol and diiscocyanate with water. Proper stabilization of the polyoly protects against oxidation during storage and transport of the polyol, as well as scorch protection during foaming.
Dragonox®-5057 can also be used in other polymers such as elastomers and adhesives , and other organic substrates.
