Description

Tridecyl Mercaptoacetate is a high-purity organic sulfur compound, specifically a long-chain alkyl ester of thioglycolic acid. This specialty chemical serves as a critical performance additive and intermediate, valued for its ability to modify polymer properties and act as a chain transfer agent. It is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product stability, rheology, and functional characteristics. The compound is supplied under stringent quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• Polymer Modification & PVC Stabilization: Acts as a secondary stabilizer and lubricant in PVC formulations, improving processing and heat stability.
• Chain Transfer Agent (CTA): Used in free-radical polymerization (e.g., acrylics, styrenics) to control molecular weight and polymer architecture.
• Lubricant & Grease Additive: Functions as an extreme pressure (EP) additive and anti-wear agent in synthetic lubricants and industrial greases.
• Intermediate for Specialty Chemicals: Serves as a key building block for synthesizing surfactants, corrosion inhibitors, and other sulfur-containing derivatives.
• Adhesive and Sealant Formulations: Imparts improved flexibility and adhesion properties in various polymer-based adhesive systems.
• Rubber Processing Aid: Used as a peptizer and plasticizer in the processing of synthetic rubbers.
