Description

Ditridecyl 3,3'-Thiodipropionate is a high-molecular-weight organosulfur compound belonging to the class of thiodipropionate antioxidants. This product serves as an effective secondary antioxidant and metal deactivator, primarily used to inhibit thermal and oxidative degradation in polymer systems. It is a critical additive for manufacturers in the plastics, lubricant, and synthetic fiber industries seeking to enhance the long-term stability and performance of their materials under demanding conditions.

Application

• Primary antioxidant and stabilizer for polyolefins such as polypropylene (PP) and polyethylene (PE).
• Synergistic stabilizer in combination with primary phenolic antioxidants for enhanced long-term heat aging (LTHA) performance in engineering plastics.
• Additive in synthetic lubricants and greases to prevent oxidation and viscosity increase.
• Stabilizer for adhesives, sealants, and elastomers to maintain flexibility and prevent embrittlement.
• Used in the production of synthetic fibers to protect against thermal degradation during processing.
• Component in food-contact compliant polymer formulations, subject to appropriate regulatory approvals.
• Additive for hot-melt adhesives and other thermoplastic applications requiring high-temperature stability.
