Applications
AO5057 used in combination with hindered phenols, such as Antioxidant-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 diisocyanate with water. Proper stabilization of the polyol protects against oxidation during storage and transport of the polyol, as well as scorch protection during foaming. It can also be used in other polymers such as elastomers and adhesives, and other organic substrates.
