In the dynamic world of material science, ensuring the longevity and performance of polymers, rubbers, and adhesives is paramount. This objective is effectively met by Antioxidant 2246, a highly efficient hindered phenolic antioxidant with CAS Number 119-47-1. Known chemically as 2,2′-methylenebis(6-tert-butyl-4-methylphenol), this additive is a cornerstone in safeguarding various organic substrates against oxidative degradation and thermal aging, which can otherwise lead to material embrittlement, discoloration, and loss of critical physical properties.

Antioxidant 2246 stands out due to its exceptional characteristics. It is a non-staining and non-discoloring compound, making it an ideal choice for clear, white, or light-colored polymeric systems where color integrity is crucial. Its inherent stability provides robust thermal protection, mitigating the effects of high processing temperatures and extending the useful life of the end products. Furthermore, its low volatility and minimal migration ensure that the protective properties are maintained throughout the material's lifecycle, without adverse effects on surface aesthetics or contact applications.

The versatility of Antioxidant 2246 makes it indispensable across a wide range of applications. In the rubber industry, it is widely utilized in natural rubber and various synthetic rubbers, including polybutadiene, styrene-butadiene, neoprene, butyl, halobutyl, and nitrile rubber, as well as in latex products and elastomers. Its efficacy extends to the plastics sector, offering superior stabilization for polyolefins such as polyethylene, polypropylene, and EVA, along with ABS, polyacetal homo- and copolymers, polyoxymethylene, chlorinated polyether, polyurethane foams, and other engineering resins. Moreover, it serves as an excellent stabilizer for hot-melt adhesives, natural rubber adhesives, sealants, caulks, and even functions as an oxidation inhibitor for fats, oils, and paraffin wax.

For enhanced protection, Antioxidant 2246 demonstrates synergistic effects when combined with other stabilizers like phosphites, thioethers, hindered amine light stabilizers (HALS), and UV absorbers. This allows for customized formulations that deliver comprehensive resistance against a multitude of environmental stressors, from heat and oxygen to UV radiation. Its regulatory clearances for specific uses in adhesives, rubber articles, and olefin polymers intended for food-contact applications underscore its safety and broad acceptance in sensitive product categories.

Typical usage concentrations for Antioxidant 2246 range from 0.05% to 1.5%, depending on the specific application, substrate, and desired level of protection. While the precise formulation should be determined through testing to simulate actual conditions, its proven performance ensures optimal results. For storage, it is recommended to keep the product in sealed containers in a cool, dry, and well-ventilated environment to maintain its efficacy over long periods.
