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.

| Antioxidant 168 | Phosphite | 31570-04-4 | 646.93 | White powder | 180-185 | Soluble in tol uene, dichlo romethane | Secondary antioxidant, decomposes peroxides, prevents yellowing | 1:1 ratio with 1010 |
| Antioxidant 1076 | Hindered Phe nol | 2082-79-3 | 530.87 | White powder/granules | 50-55 | Soluble in oils, ace tone | Low migration, complies with food contact standards | 0.05%-0.3% |
| BHT | Synthetic Phe nol | 128-37-0 | 220.35 | White powder | 69-72 | Soluble in oils, ethanol | Low cost, volatile (not suitable for high temps) | 0.01%-0.1% |
| DLTDP | Thioester | 123-28-4 | 514.80 | White flakes/powder | 39-42 | Soluble in oils, ace one | Secondary antioxidant, provides sulfur for synergy | 0.1%-0.3% |
| Antioxidant 626 | Phosphite | 26741-53-7 | 604.76 | White powder | 160-175 | Soluble in tol uene, xylene | Hydrolysis-resistant, excellent high-temperature processing stability | 0.2%-0.5% |
Antioxidants inhibit oxidation reactions and delay material aging, widely used in the following fields:
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.
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.
Adhesives/Coatings: Prevent brittleness or discoloration caused by resin oxidation post-curing.
Elastomers: Maintain flexibility and strength of silicone, polyurethane, and similar materials.
| Factors | Guidelines |
| Material Type | 1.Polyolefins (PP/PE): Hindered phe nol (1010) + phosphite (168) 2.Engineering plastics (PC/PET): Hydrolysis-resistant types (626) |
| Process Conditions | 1.High-temperature processing (>200°C): Low-volatility antioxidants (e.g., 1010) 2.Outdoor exposure: Combine with UV stabilizers or metal deactivators |
| Regulatory Compliance | 1.Food contact materials: FDA/EU 10/2011-certified antioxidants (e.g., 1076) 2.Environmental requirements: Avoid restricted components (e.g., BHT) |
| Cost Efficiency | 1.Low-cost scenarios: BHT (note volatility and restrictions) 2.High-performance scenarios: Blended systems (1010+168+DLTDP) |
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%.
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).
| Issue | Root Cause | Solution |
| Yellowing of plastics | Oxidation-induced chromophores | Add phosphites (e.g., 168) to decompose peroxides |
| Increased lubricant viscosity | Oxidation-generated sludge | Increase phe nol antioxidant dosage (0.3%-1.0%) |
| Surface cracking in rubber | Post-vulcanization oxidative aging | Blend BHT + DLTDP (0.1% + 0.1%) |
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).
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.
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.
