Description

Thiobis[2-(1,1-Dimethylethyl)-5-Methyl-4,1-Phenylene] Bis[3-(Dodecylthio)Propionate] is a high-performance, sulfur-based antioxidant and stabilizer widely used in polymer manufacturing. This compound is valued for its exceptional ability to prevent thermal and oxidative degradation, thereby significantly extending the service life of finished products. It is an essential additive for producers of polyolefins, elastomers, and other synthetic materials requiring long-term stability under demanding conditions. The product is supplied under strict quality control to ensure batch-to-batch consistency for industrial applications.

Application

• Primary antioxidant and stabilizer in polypropylene (PP) and polyethylene (PE) production.
• Thermal stabilizer for engineering plastics and synthetic rubbers to prevent chain scission and cross-linking.
• Additive in adhesives and sealants to enhance durability and resistance to heat aging.
• Stabilizing component in lubricants and greases to inhibit oxidation and viscosity change.
• Used in wire and cable insulation compounds to protect against thermal degradation during processing and use.
• Co-stabilizer in color masterbatches to prevent pigment-catalyzed degradation of the polymer matrix.
