Description

Dihexadecenyl 3,3'-Thiobispropionate is a high-purity, synthetic antioxidant belonging to the class of thio-based stabilizers. This compound is valued for its exceptional ability to inhibit oxidative degradation and extend the functional lifespan of sensitive materials. It is primarily sought after by formulators and manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product stability and performance.

Application

• Polymer Stabilization: Acts as a secondary antioxidant and metal deactivator in polyolefins (e.g., polyethylene, polypropylene), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Grease Additive: Used as an antioxidant in industrial lubricants, gear oils, and greases to reduce sludge formation, control viscosity increase, and extend oil drain intervals.
• Adhesive & Sealant Formulations: Enhances the shelf-life and thermal stability of hot-melt adhesives, pressure-sensitive adhesives, and elastomeric sealants.
• Fat & Oil Stabilization: Employed as a food-grade or technical-grade antioxidant (where compliant) to prevent rancidity in edible oils, animal fats, and lipid-based ingredients.
• Cosmetic & Personal Care: Serves as a stabilizer in formulations containing unsaturated oils and butters to prevent odor and color development.
• Fuel & Petrochemical Additive: Helps improve the oxidation stability of biofuels, biodiesel, and other middle distillates.
