Description

Thiobis(tert-Octane) CAS NO 94247-13-9 is a specialized organosulfur compound, specifically a thioether, known for its role as a high-performance antioxidant and stabilizer in polymer systems. Its molecular structure provides exceptional efficacy in scavenging free radicals and preventing thermal and oxidative degradation, thereby extending the service life of critical materials. This product is essential for formulators and manufacturers in the plastics, lubricant, and specialty chemical industries seeking to enhance product durability and performance under demanding conditions.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (e.g., PP, PE) to prevent thermal-oxidative degradation during processing and long-term use.
• Lubricant & Fuel Additive: Acts as an antioxidant and anti-wear agent in synthetic lubricants, greases, and industrial fuels to improve stability and reduce sludge formation.
• Rubber Industry: Used in the compounding of synthetic rubbers (e.g., SBR, EPDM) to protect against heat aging and maintain elastomeric properties.
• Adhesive & Sealant Formulations: Enhances the shelf-life and thermal stability of hot-melt and reactive adhesive systems.
• Specialty Chemical Intermediate: Serves as a key building block or precursor in the synthesis of more complex sulfur-containing specialty chemicals.
• Coating Resins: Incorporated into coating formulations to protect against UV and oxidative degradation, preserving film integrity and color.
