Usage

Description

Antioxidant 5057, also known as Irganox 5057, is a 100% active liquid aromatic amine antioxidant specifically designed for processing and long-term thermal stabilization of various materials. It is composed of benzenamine, N-phenyl-, reaction products with 2,4,4-trimethylpentene. Antioxidant 5057 is characterized by its low volatility, high efficiency, low toxicity, and environmental safety. It offers outstanding thermal stability and strong high-temperature oxidation resistance, making it a valuable additive in the manufacturing and stabilization of polymers.

Uses

Used in the Plastics and Elastomers Industry:
Antioxidant 5057 is used as a processing stabilizer and long-term thermal stabilizer for elastomers, polyols, and polyurethane. It helps prevent thermal degradation of polymers, ensuring the durability and longevity of the final product.
Used in the Manufacturing of Flexible Polyurethane Slabs:
Antioxidant 5057 is used as a co-stabilizer in combination with hindered phenols, such as Irganox 1135, in the production of flexible polyurethane slabstock foams. It plays a crucial role in preventing core discoloration or scorching, which can result from the exothermic reaction of diisocyanate with polyol and diisocyanate with water. Proper stabilization of the polyol with Antioxidant 5057 protects against oxidation during storage and transport, as well as providing scorch protection during the foaming process.
Used in Other Polymers and Adhesives:
Antioxidant 5057 is also utilized in other polymers, such as elastomers and adhesives, to enhance their thermal stability and resistance to high-temperature oxidation. Its unique liquid properties make it convenient for measurement and transportation, contributing to its widespread use in various applications.
Used in Organic Substrates:
In addition to its applications in the plastics and elastomers industry, Antioxidant 5057 is also used in other organic substrates to provide thermal stability and protection against oxidation, ensuring the quality and performance of the final product.

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.
