Description

Bis[3-[3,5-Di(tert-Butyl)-4-Hydroxyphenyl]Propionic Acid]2,2-Dimethyltrimethylene Ester is a high-performance, sterically hindered phenolic antioxidant widely used to inhibit oxidative degradation in polymers and other organic materials. Its primary value lies in providing exceptional long-term thermal stability and color retention, significantly extending the service life of finished products. This compound is essential for manufacturers in the plastics, rubber, synthetic fiber, and lubricant industries seeking to enhance product durability and performance under demanding conditions.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, PE), polystyrene, ABS, and engineering plastics to prevent thermal-oxidative degradation during processing and end-use.
• Rubber Industry: Protects synthetic rubbers (SBR, BR, NBR) and natural rubber from aging, maintaining elasticity and mechanical properties.
• Adhesives & Sealants: Enhances the shelf-life and performance stability of hot-melt adhesives, pressure-sensitive adhesives, and various sealants.
• Lubricants & Greases: Used as an antioxidant additive in engine oils, industrial lubricants, and greases to reduce sludge formation and viscosity increase.
• Synthetic Fibers: Incorporated into polypropylene and polyester fibers to prevent strength loss and yellowing caused by heat and light exposure.
• Food Contact Materials: Suitable for use in polymer applications that comply with relevant regulations for food packaging and handling equipment.
• Masterbatch & Compound Production: A key ingredient in antioxidant concentrates and polymer compounds for uniform additive distribution.
