When incorporated into styrene polymers like polystyrene and styrene-butadiene copolymers, it maintains the physical properties of these materials over time. Additionally, it is employed in wire and cable insulation materials to improve oxidative stability and heat resistance, resulting in longer lifespan and better performance of the final products. In summary, Antioxidant 1024 significantly contributes to the stability and durability of various polymer products. Its versatility makes it suitable for use in multiple industries, including packaging, automotive, construction, electronics, and wire and cable. Polymer manufacturers benefit from its effectiveness as an additive to enhance the performance and longevity of their products. ²

Safety

Although antioxidant 1024 is widely used in the production of polymers, it does possess certain safety risks that need to be carefully considered. Firstly, antioxidant 1024 is considered to be irritating to the eyes and skin. Contact with antioxidant 1024 may cause irritation of the eyes, skin, and respiratory system. Therefore, it is important to wear appropriate protective gear and avoid direct contact with antioxidant 1024 during handling and usage. Secondly, antioxidant 1024 is flammable, and it can catch fire if exposed to open flames or high temperatures. Therefore, it should be stored in a cool and dry place away from sources of fire or ignition sources. Thirdly, antioxidant 1024 is toxic if inhaled or ingested. Exposure to high concentrations of antioxidant 1024 may cause irritation of the respiratory tract, nausea, vomiting, and other adverse health effects. If exposed to antioxidant 1024, it is important to immediately remove the source of exposure, move to fresh air, and seek medical attention if necessary. Overall, antioxidant 1024 does possess certain safety risks that need to be carefully considered during handling and usage. ³
