Dual Functionality: Combines efficient radical-scavenging (antioxidant) capability with metal deactivation, providing enhanced protection against oxidative degradation.
Outstanding Thermal Stability: Maintains excellent performance under high-temperature processing and long-term thermal exposure.
低挥发性 & Migration: Ensures minimal loss during processing and long-term use, improving durability and product lifespan.
Non-Staining & Non-Discoloring: Suitable for applications requiring high color stability and clean 外观.
Effective Metal Deactivation: Chelates trace metal ions (e.g., copper, iron), reducing catalytic oxidation and preventing premature material degradation.
Enhanced Polymer Protection: Improves resistance to thermal aging, oxidation, and mechanical stress in polymers and elastomers.
Widely used in various elastomers. Applied to plastic masterbatch such as polyethylene, polypropylene, and polyvinyl chloride. It can be used as an antioxidant for polyurethane foam plastics, rubber wires, cables, food packaging materials and adhesives, especially in neoprene colored cable sheaths.
Sinanox® 405 has remarkable heat resistance, light resistance and aging resistance. It can be used as light resistant and anti-aging antioxidant in polyether and its foam plastics, and also as lubricating oil antioxidant.
Especially effective in protecting against aging caused by high heat, light, etc. in chloroprene rubber, acrylic rubber, polyether polyols, etc.
