Antioxidant 101

Product Overview

Antioxidant 101 represents a advanced class of hindered phenol esters engineered for high-performance polymer stabilization. Chemically identified as [4-tert-butyl-2-(5-tert-butyl-2-oxo-3H-1-benzofuran-3-yl)phenyl] 3,5-ditert-butyl-4-hydroxybenzoate, this specialty chemical functions as a highly efficient carbon-centered free radical scavenger. Its primary role in industrial formulations is to preserve the integrity of polymer chains during processing and extended service life. By effectively mitigating oxidative degradation, this additive ensures consistent Melt Flow Index (MFI) stability and significantly minimizes color development, making it a critical component for manufacturers demanding high clarity and aesthetic quality in plastic products.

Industrial Applications

The versatility of Antioxidant 101 allows it to serve across multiple demanding sectors within the plastics and rubber industry. Its unique chemical structure provides distinct advantages over traditional stabilization systems:

• Polystyrene Stabilization: Effectively reduces monomer residue in polystyrene and its copolymers, enhancing overall material purity and performance.
• BOPP Processing: Improves processing characteristics, anti-aging properties, and optical performance in Biaxially Oriented Polypropylene films.
• Polyurethane Formation: Exhibits excellent anti-phenolic yellowing performance, improving anti-scorching properties during the PU forming process.
• Synergistic Systems: When combined with phosphite antioxidants and other hindered phenols, it boosts anti-aging performance while potentially reducing the required dosage of primary antioxidants.
• Thermal Resistance: Demonstrates robust thermal stability with TGA showing 10% weight loss only at 323℃, suitable for high-temperature processing environments.

Storage And Handling

To maintain optimal quality and efficacy, Antioxidant 101 should be stored in a cool, dry environment away from direct sunlight and moisture. Containers must remain tightly closed when not in use to prevent contamination or absorption of atmospheric humidity.
