Antioxidants is a class of chemical additives used to inhibit or delay the oxidative degradation of materials, mainly through the blocking of free radical chain reaction, decomposition of peroxides or passivation of metal ions and other ways to play a role. In the chemical industry, antioxidants are indispensable functional additives in polymer materials (plastics, rubber, fibers), lubricants, fuels and industrial chemicals, which can significantly extend the service life of the materials and improve product stability.

I. Core Applications of Chemical Antioxidants

Antioxidants inhibit oxidation reactions and delay material aging, widely used in the following fields:

1. Polymer Materials

• Plastics: Prevent thermal oxidative degradation of polypropylene (PP), polyethylene (PE), polycarbonate (PC), etc., during processing or use, extending product lifespan.
• Rubber: Delay oxidative aging during vulcanization of tires, seals, etc., avoiding hardening and cracking.
• Synthetic Fibers: Protect nylon (PA) and polyester (PET) from molecular chain breakage during high-temperature spinning.
  

  

  
  

  

  

   

2. Lubricants and Fuels

• Lubricants: Inhibit oxidation of base oils to prevent acid and sludge formation, extending oil change intervals.
• Fuels: Prevent oxidation-induced gum formation in gaso line and die sel during storage, avoiding engine system blockages.

3. Industrial Chemicals

• Adhesives/Coatings: Prevent brittleness or discoloration caused by resin oxidation post-curing.
• Elastomers: Maintain flexibility and strength of silicone, polyurethane, and similar materials.

II. Application Guide

1. Antioxidant Selection Principles

2. Typical Application Guidelines

• Polyolefins (PP/PE)
  • Recommended Antioxidants: 1010 (primary) + 168 (secondary), 1:1 ratio
  • Dosage: 0.1%-0.5% (by total weight)
  • Effect: Extends thermal aging resistance by 50%-200%.
• Engineering Plastics (PC/PET)
  • Recommended Antioxidant: 626 (hydrolysis-resistant phosphite)
  • Dosage: 0.2%-0.5%
  • Effect: Prevents yellowing during processing and maintains transparency.
• Rubber Products
  • Recommended Antioxidants: BHT (primary) + DLTDP (secondary)
  • Dosage: 0.05%-0.2%
  • Effect: Delays oxidative aging during vulcanization, reducing cracks.
• Lubricants
  • Recommended Antioxidants: Amine-based (e.g., T501) + phe nol-based (e.g., 1076)
  • Dosage: 0.1%-1.0%
  • Effect: Extends oil service life by 30%-50%.

3. Key Considerations

• Synergistic Effects: Combine primary/secondary antioxidants (e.g., 1010+168) for optimal performance.
• Thermal Stability: Use low-volatility antioxidants (e.g., 1010) for high-temperature processing to minimize loss.
• Migration Resistance: Select low-migration types (e.g., 1076) for food packaging.
• Regulatory Compliance: Verify restrictions (e.g., BHT limitations in the EU).

4. Common Issues & Solutions

III. Future Development Prospects

1. Technological Trends

• High-Efficiency Multifunctionality: Develop “all-in-one” additives with antioxidant, UV-resistant, and flame-retardant properties.
• Green & Sustainable Solutions: Promote natural antioxidants (e.g., rosemary extract) and halogen/phosphorus-free formulations to comply with regulations like EU REACH.
• High-Temperature Demand Growth: New energy vehicles and 5G electronics drive R&D for high-temperature-resistant antioxidants (>300°C, e.g., high-MW hindered phe nols).
• Optimized Compounding: Enhance synergy via molecular design (e.g., nano-encapsulation).

2. Market Drivers

• Plastic Replacement of Metals: Expanding use of engineering plastics in automotive and aerospace industries boosts antioxidant demand.
• Stricter Environmental Regulations: Restrictions on traditional antioxidants (e.g., BHT) push adoption of eco-friendly alternatives.
• Emerging Markets: Rapid industrialization in Asia-Pacific (China, India) positions the region as the largest consumer market.

3. Challenges & Strategies

• Cost Pressure: High costs of natural antioxidants require scaling production for cost reduction.
• Technical Barriers: Complex synthesis of high-temperature/hydrolysis-resistant antioxidants demands industry-academia collaboration.
• Recycled Material Needs: Redesign antioxidant strategies for recycled plastics due to additive loss during reprocessing.

4. Future Opportunities

• Bio-Based Antioxidants: Develop biodegradable antioxidants from plant extracts (e.g., green tea polyphe nols).
• Smart Manufacturing: Use AI algorithms to optimize antioxidant blends for customized solutions.
• Extreme Environment Applications: Meet ultra-high stability requirements for deep-sea or aerospace materials.
