Antioxidant 412S

Product Overview

Antioxidant 412S is a highly effective secondary antioxidant belonging to the advanced thioester family, specifically engineered to provide exceptional thermal stability during the processing and long-term service life of various organic polymers. This high molecular weight sulfur-containing compound is characterized by its remarkably low volatility, which ensures that it remains within the polymer matrix even under elevated processing temperatures typical of modern extrusion and molding operations. Unlike primary antioxidants that scavenge free radicals directly, Antioxidant 412S functions primarily by decomposing hydroperoxides, thereby preventing the initiation of oxidative degradation chains before they can cause significant material damage.

The chemical structure features multiple dodecylthio groups attached to a central core, providing multiple active sites for radical scavenging and peroxide decomposition. This unique architecture contributes to its high performance in demanding applications where standard antioxidants might fail due to evaporation or extraction. Our manufacturing process ensures high purity levels, minimizing impurities that could affect the color or mechanical properties of the final polymer product.

Industrial Applications

This product is extensively used in the stabilization of polyolefins such as polypropylene and polyethylene, where it significantly extends the service life of the material. It is also fully compatible with engineering thermoplastics including ABS and PC-ABS blends, making it versatile for various industrial sectors. The additive is particularly valuable in applications requiring high heat resistance, such as automotive components under the hood, household appliances like washing machines and dishwashers, and thermal resistant pipes used in construction infrastructure.

Furthermore, it is suitable for film production where clarity and longevity are critical for packaging solutions. The low leaching properties make it an ideal choice for items that may come into contact with liquids or require long-term durability without surface blooming. In combination with hindered phenolic antioxidants, it achieves a synergistic performance that exceeds the sum of individual components, providing comprehensive protection against thermo-oxidative degradation.

Key Performance Advantages

• Superior synergistic effect when combined with hindered phenolic antioxidants for maximum protection.
• Extremely low volatility prevents loss during high-temperature extrusion and processing cycles.
• Excellent resistance to extraction by water and organic solvents ensures long-term stability.
