Usage

Description

Antioxidant 5057 has low toxicity and is safe to use; compared with phosphites, it has no ash, no phosphorus, and does not pollute the environment; it also has unique liquid properties and is convenient for measurement and transportation. It has the characteristics of outstanding thermal stability and strong high temperature oxidation resistance. At the same time, it has good compatibility with oil products.

Uses

Antioxidant 5057 is a 100% active liquid aromatic amine antioxidant for processing and long-term thermal stabilization. It contains benzenamine, N-phenyl-, reaction products with 2,4,4-trimethylpentene. Antioxidant 5057 has low volatility and is highly efficient and prevents thermal degradation of polymers. Used in elastomers, polyols and polyurethane. It is used in manufacturing of flexible polyurethane slabstock foams. Its typical dosage level is 0.1-0.4%.

Application

Irganox 5057 is used in combination with hindered phenols, such Irganox 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. Irganox 5057 can also be used in other polymers such as elastomers and adhesives, and other organic substrates.

benefits

Irganox 5057 is highly efficient and prevents, even at low concentrations, thermal degradation of polymers. Irganox 5057, when used in combination with a phenolic antioxidant, such as the liquid Irganox 1135, is very active in preventing scorching of polyurethane flexible foams.

Flammability and Explosibility

Notclassified

Safety

Irganox 5057 exhibits a very low order of oral toxicity and does not present any abnormal problems in its handling or general use.
