Antioxidant 80

Product Overview

Antioxidant 80, also known commercially as Sumilizer GA 80, represents a class of high molecular weight hindered phenolic antioxidants engineered for superior polymer protection. This advanced chemical additive features a unique spiro structure that enhances its compatibility and permanence within various polymer matrices. Designed for demanding industrial applications, it effectively scavenges free radicals generated during thermal processing and long-term usage, thereby extending the service life of plastic materials.

As a primary antioxidant, this compound is particularly valued for its ability to suppress initial color formation while providing robust heat stability. Its high molecular weight ensures low volatility and minimal extraction, making it an ideal choice for products requiring compliance with strict safety and durability standards. Manufacturers across the globe rely on this material to maintain the mechanical integrity and aesthetic quality of their polymer formulations.

Key Specifications

Industrial Applications

This antioxidant is versatile and suitable for a wide range of thermoplastic polymers. It is highly recommended for use in polypropylene (PP), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE). Additionally, it performs exceptionally well in engineering plastics such as polybutylene terephthalate (PBT), polyoxymethylene (POM), polyamide (PA), and nylon. The additive is also effective in protecting acrylonitrile butadiene styrene (ABS), high impact polystyrene (HIPS), and polyurethane (PU) systems.

• Automotive components requiring long-term thermal stability.
• Packaging films where color clarity is critical.
• Fiber production needing resistance to processing heat.
• PU and PET coatings exposed to severe environmental conditions.

Usage And Synergy

The recommended usage concentration typically ranges from 0.1% to 0.5%, depending on the specific polymer substrate and the severity of the processing conditions. For optimal performance, Antioxidant 80 exhibits remarkable synergy when combined with thioether co-stabilizers, such as secondary antioxidants. This combination provides a comprehensive stabilization package that protects against both processing degradation and long-term oxidative aging. Proper dispersion during compounding is essential to achieve the desired protective effects.

Storage And Handling

To maintain product integrity, containers should be kept tightly closed in a cool, dry environment. Avoid exposure to direct sunlight and moisture. When handled according to standard industrial hygiene practices, this material offers a stable and reliable solution for polymer stabilization needs. Our company ensures consistent quality through rigorous testing and provides comprehensive documentation including Certificates of Analysis for every batch.
