Antioxidant 1098, also known as Irganox 1098, is a chemical compound classified as a phenolic antioxidant. It is part of a group of stabilizers used to protect materials from oxidative degradation. Specifically, it is a high-performance hindered phenol that provides long-term protection against the damaging effects of oxygen and heat on various materials, primarily in polymers, plastics, and elastomers.
The main functions of Irganox 1098 are:
Free Radical Scavenging: It works by reacting with free radicals that are generated during the oxidation process, neutralizing them before they can cause damage to the polymer structure.
Thermal Stability: It helps prevent the polymer or material from breaking down or losing properties due to prolonged exposure to heat, making it especially useful in high-temperature applications.
Protection from Environmental Degradation: It enhances the weathering resistance of materials exposed to ultraviolet (UV) light, preventing discoloration, embrittlement, and loss of strength over time.
Antioxidant 1098, also known as Irganox 1098, is a commonly used antioxidant in the plastics and polymer industry. Its main application is to prevent oxidative degradation in various materials, especially polymers, by inhibiting the formation of free radicals that can cause the breakdown of materials under heat and light.
Some key applications include:
Polymer Stabilization: Irganox 1098 is used in polymers such as polyethylene (PE), polypropylene (PP), polystyrene (PS), and other engineering plastics to improve their long-term stability and resistance to aging, discoloration, and embrittlement due to exposure to heat and oxygen.
Plastics Manufacturing: It is commonly added during the extrusion or injection molding processes to ensure that the final product maintains its mechanical and visual properties over time.
Rubber Industry: It is used to stabilize rubber compounds, improving their durability, performance, and resistance to oxidative damage.
Lubricants and Oils: It can also be used in lubricants and oils to prevent oxidation during storage and use, extending the life of the product.
Food Packaging: Irganox 1098 can be found in food packaging materials to prevent the degradation of the packaging material from exposure to air, ensuring that the packaging maintains its protective qualities.
Overall, the antioxidant helps in prolonging the lifespan and maintaining the quality of materials in various industries.
