Dragonox® 5057

Dragonox® 5057 is used as an excellent co-stabilizer in polyurethane foams, such as in combination with hindered phenols like Dragonox® 1135. Core discoloration or scorching results from the exothermic reactions of a diisocyanate with polyol and a diiscocyanate with water during the manufacture of flexible polyurethane slabstock foams. Proper stabilization of these polyols using Dragonox® 5057 protects against oxidation during storage and transport and also provides scorch protection during foaming. This product can also be used with other polymers, such as elastomers, adhesives, and other organic substrates.
