Introduction
UV Absorbers
1. Definition & Mechanism
UV absorbers are additives that protect materials from UV degradation by:
- Absorbing harmful UV radiation (290–400 nm)
- Converting it into harmless heat energy
- Preventing chain reactions (e.g., polymer breakdown, color fading)
2. Key Applications
| Industry | Protected Materials | Common UV Absorbers |
|---|---|---|
| Polymers | Plastics (PP, PVC), rubber | Benzotriazoles (e.g., Tinuvin 328) |
| Coatings | Paints, automotive finishes | Hindered Amine Light Stabilizers (HALS) |
| Textiles | Synthetic fibers, outdoor fabrics | Hydroxyphenyl-triazines (e.g., Cyasorb) |
| Cosmetics | Sunscreens, skincare | Octinoxate, Avobenzone |
3. Advantages
- Material Protection:
- Extends product lifespan by 50–300%
- Prevents yellowing, cracking, and loss of mechanical strength
- Performance:
- Broad-spectrum coverage (UVA + UVB)
- Low migration (for long-term stability)
4. Technical Specifications
| Property | Typical Value |
|---|---|
| UV Absorption | 290–400 nm (tailorable) |
| Thermal Stability | Up to 300°C (for plastics) |
| Compatibility | Works with most resins/polymers |
| Load Rate | 0.1–2.0% by weight |
