Description

Dihexyl 3,3'-Thiodipropionate is a high-performance organosulfur antioxidant and secondary stabilizer. This compound is valued for its ability to effectively interrupt the degradation cycle of polymers, thereby extending their service life and maintaining their physical properties. It is a critical additive for manufacturers in the plastics, rubber, and lubricant industries seeking to enhance the thermal stability and durability of their products.

Application

• Primary antioxidant synergist in polyolefins such as polypropylene (PP) and polyethylene (PE).
• Thermal stabilizer for synthetic rubbers and elastomers to prevent premature aging.
• Additive in lubricating oils and greases to inhibit oxidation and sludge formation.
• Stabilizing component in adhesives and sealants to ensure long-term performance.
• Used in the production of food-contact compliant polymers where regulatory-approved additives are required.
• Enhances the light stability of materials when used in combination with primary antioxidants and UV stabilizers.
