The rubber industry relies heavily on additives that can protect its products from the environmental factors that cause degradation and premature failure. Oxidation, driven by heat and oxygen, is a primary concern, leading to loss of elasticity, cracking, and reduced service life. Antioxidant 2246 (CAS 119-47-1) is a highly effective and widely used phenolic antioxidant that plays a crucial role in preserving the integrity and performance of rubber materials. As a dedicated supplier, we provide high-quality Antioxidant 2246 to rubber manufacturers worldwide.

Understanding Antioxidant 2246 in Rubber Applications

Antioxidant 2246, chemically known as 2,2′-Methylenebis(6-tert-butyl-4-methylphenol), is a sterically hindered bisphenolic compound. Its structure is optimized to scavenge free radicals generated during the processing and service life of rubber. These radicals initiate auto-oxidation, a chain reaction that leads to the breakdown of polymer chains. By donating a hydrogen atom to peroxy and alkoxy radicals, Antioxidant 2246 effectively terminates these chain reactions, preventing significant damage.

Key Benefits for Rubber Products

  • Excellent Thermal Oxidation Resistance: Rubber products, especially those in automotive or industrial applications, are often exposed to elevated temperatures. Antioxidant 2246 provides robust protection against heat-induced oxidation, extending the product's operational lifespan.
  • Non-Staining and Non-Discoloring: A critical advantage for many rubber goods, particularly those requiring specific aesthetic qualities (e.g., white or light-colored footwear, seals, or medical devices), is that Antioxidant 2246 does not cause significant color changes.
  • Good Compatibility with Various Rubbers: It is compatible with a wide range of elastomers, including natural rubber (NR), styrene-butadiene rubber (SBR), polybutadiene rubber (BR), nitrile rubber (NBR), and latex. This broad compatibility makes it a versatile choice for diverse rubber formulations.
  • Minimal Impact on Vulcanization: Unlike some other antioxidants, Antioxidant 2246 typically has minimal interference with the vulcanization process, ensuring predictable cure rates and final physical properties.
  • Low Volatility: Its low volatility ensures it remains within the rubber matrix during processing and use, providing long-term protection against degradation.
