Applications of AO168 in Medical and Food Contact Materials
As global requirements for:
- Food safety
- Medical safety
- Low migration
- Low VOC
- Long-term stability
continue to increase, the polymer additive industry is moving toward:
Higher purity, lower impurities, and stricter regulatory standards
Among these additives:
AO168 (Antioxidant 168)
as one of the most important phosphite secondary antioxidants, has been widely used in:
- Medical plastics
- Food packaging
- Infusion devices
- Medical tubing
- Baby products
- High-end food containers
and many other applications.
1. Why Medical and Food Materials Need AO168
Medical and food-contact materials are commonly made from:
- PP
- PE
- PET
- EVA
- TPU
- Engineering plastics
During:
- High-temperature sterilization
- Extrusion
- Injection molding
- Long-term storage
these materials are prone to:
- Thermal oxidative degradation
- Yellowing
- Odor generation
- Molecular chain scission
Therefore:
Highly effective stabilization systems are essential
AO168 can:
Rapidly decompose hydroperoxides (ROOH)
and prevent continuous polymer oxidation.

AO168 is widely used in:
- Food packaging films
- Beverage caps
- Microwave food containers
- Fresh-keeping packaging
- High-barrier packaging
Its key advantages include:
- Low volatility
- Low odor
- Excellent processing stability
- Strong synergy with primary antioxidants
Food Packaging Application Photos
When AO168 is used in food contact materials, it typically needs to comply with:
- U.S. FDA food contact regulations
- EU 10/2011
- REACH
- RoHS
Recent studies indicate that:
Migration control
of AO168 and its degradation byproducts is receiving increasing attention.
As a result:
High-purity AO168 is becoming an industry trend
3. Applications of AO168 in Medical Materials
Medical plastics require even stricter stabilization systems because they often undergo:
- Steam sterilization
- Ethylene oxide sterilization
- Long-term human contact
- Extended storage periods
Applications include:
- Infusion devices
- Syringes
- Medical tubing
- Hemodialysis materials
- Medical packaging
Medical Material Application Photos
Traditional industrial-grade AO168 generally has:
Purity ≥99%
However, future medical and food-grade markets may increasingly require:
| Application Area | Future Recommended Purity |
|---|---|
| General plastics | ≥99% |
| Food contact materials | ≥99.3% |
| High-end food packaging | ≥99.5% |
| Medical materials | ≥99.5–99.8% |
| Advanced medical devices | ≥99.8% |
Why Higher Purity Will Be Required
Because:
Impurities and degradation byproducts
may lead to:
- Increased odor
- Higher VOC levels
- Yellowing
- Increased migration risks
In particular:
- Free phenols
- Oxidation byproducts
- Hydrolysis impurities
can affect:
Food safety and biocompatibility
5. Future Certifications and Compliance Requirements
Future high-end AO168 products may require:
| Certification / Regulation | Purpose |
|---|---|
| FDA | Food contact safety |
| EU 10/2011 | EU food contact compliance |
| REACH | European chemical regulation |
| RoHS | Restriction of hazardous substances |
| ISO 10993 | Medical biocompatibility |
| USP Class VI | Medical plastic testing |
| GMP systems | Medical and food manufacturing management |
6. Future Development Trends of AO168
Future market demand for AO168 will increasingly focus on:
- High purity
- Low VOC
- Low migration
- Low odor
- High hydrolysis resistance
- Long-term stability
In particular:
Medical and food contact materials
will become one of the most important high-end application areas for AO168.
