Future Applications of AO168 in New Energy Vehicles: The Key to Low VOC and Long-Term Stability
With the rapid growth of the global new energy vehicle (NEV) industry, automotive materials are evolving from traditional plastics toward:
- High heat resistance
- Long service life
- Low VOC
- Recyclability
- High safety performance
Especially in critical components such as:
- Battery pack systems
- High-voltage connectors
- High-voltage cables
- Electronic control modules
- Lightweight structural parts
polymer materials are continuously exposed to:
- High temperatures
- Electrical heat accumulation
- Oxidation
- UV aging
- Long-term thermal cycling
As a result:
Stabilization systems have become a core technology in NEV plastics
Among them:
AO168 (Antioxidant 168)
is gradually becoming a key processing stabilizer in NEV materials.
1. Why NEV Materials Need AO168
Compared with conventional vehicles, plastics used in NEVs require:
- Higher thermal resistance
- Longer service life
- More stringent electrical safety
- Lower VOC emissions
Especially near high-voltage systems, plastic components may remain under:
- 120–150°C
- Oxygen-rich environments
- Continuous thermal cycling
for extended periods.
Without an effective stabilization system, polymers may suffer from:
- Yellowing
- Brittleness
- Cracking
- Reduced insulation performance
- Smoke generation
- Odor issues
Core Function of AO168
AO168 is a:
Phosphite secondary antioxidant
Its primary role is to:
Decompose hydroperoxides (ROOH) in polymers
and prevent continuous thermal oxidative degradation.
