1. Product Overview & Specifications

Antioxidant 5057 (CAS 68411-46-1), also known as Irganox 5057 or Antioxidant ODP, is a liquid hindered amine antioxidant widely used in polymer stabilization. It combines low volatility, environmental safety (non-phosphorus, ash-free), and excellent compatibility with industrial oils and polymers.

2. Key Applications

• Polyurethane Foams: Prevents scorching during production and discoloration in automotive/furniture applications.
• Lubricants: Enhances oxidation resistance under high-temperature conditions.
• Plastics & Elastomers: Protects against thermal degradation in processing and storage.
• Textile Coatings: Minimizes color contamination in polyurethane-coated fabrics.

3. Usage Guidelines

• Recommended Dosage: 0.1–0.4% by weight, depending on application requirements.
• Synergistic Combinations: Use with phenolic antioxidants (e.g., Irganox 1135) or stabilizers (e.g., phosphites) for enhanced performance.
• Storage: Store in sealed containers at room temperature, away from light and moisture.
• Safety: Low toxicity; follow standard industrial handling protocols (gloves, goggles).
