Future Applications of Antioxidant 168: Synergistic Stabilization Systems for Advanced Polymer Materials
As the global polymer industry moves toward higher performance, sustainability, and multifunctional materials, traditional antioxidant systems are also evolving rapidly. Among the many processing stabilizers used in plastics and elastomers, Antioxidant 168 (AO 168) continues to play a critical role due to its excellent thermal stabilization performance and outstanding synergistic effects with other additives.
Historically, AO 168 has been widely used in polyolefins, engineering plastics, synthetic rubber, adhesives, and coatings. However, future material trends suggest that the role of AO 168 will expand far beyond conventional applications.
Instead of functioning as a standalone additive, AO 168 is increasingly becoming part of integrated stabilization systems designed for advanced materials used in electric vehicles, renewable energy, biodegradable plastics, high-frequency electronics, and nanocomposites.
AO 168 + Hindered Phenolic Antioxidants
The most established antioxidant system remains the combination of AO 168 with hindered phenolic antioxidants such as AO 1010 and AO 1076.
This synergistic system works because:
- Primary antioxidants eliminate free radicals
- AO 168 decomposes hydroperoxides
- Together they improve both processing stability and long-term aging resistance
This combination is widely used in:
- Polypropylene (PP)
- Polyethylene (PE)
- Engineering plastics
- Synthetic elastomers
- High-temperature polymer compounds
As polymer processing temperatures continue to increase, this classic stabilization system will remain essential for modern polymer manufacturing.
Future Application: Electric Vehicle (EV) Materials
One of the most promising future growth areas for AO 168 is the electric vehicle industry.
Modern EV systems require polymers capable of withstanding:
- Continuous heat exposure
- Electrical insulation stress
- Long-term thermal aging
- Low VOC requirements
AO 168 is expected to become increasingly important in:
- Battery housing materials
- High-voltage connectors
- Charging systems
- Lightweight automotive plastics
- Cable insulation compounds
- PA66
- PBT
- PC/ABS
- Modified PP
- PPO blends
Future EV materials will increasingly rely on AO 168 combined with phenolic antioxidants and flame-retardant systems to improve long-term reliability.

- Processing stabilizers
to provide long-term environmental durability.
AO 168 + Flame Retardants
Future flame-retardant polymers represent another major opportunity for AO 168.
Many flame retardants accelerate polymer degradation during high-temperature compounding. AO 168 helps improve:
- Melt stability
