Why High Alumina Glass is Superior to Middle Alumina Glass in Screen Protectors
When choosing screen protectors for smartphones, tablets, or other electronic devices, glass quality matters. Among the most common materials used in tempered glass films are high alumina glass and middle alumina glass. Understanding their differences can help both wholesalers and consumers make smarter purchasing decisions.
What is Alumina Glass?
Alumina glass, or aluminosilicate glass, is a type of chemically strengthened glass that contains aluminum oxide (Al₂O₃). It offers better durability, scratch resistance, and thermal stability compared to regular soda-lime glass.
Key Differences Between High Alumina and Middle Alumina Glass
| Feature | High Alumina Glass | Middle Alumina Glass |
|---|---|---|
| Alumina Content | > 16% | 9–15% |
| Scratch Resistance | ★★★★★ | ★★★★☆ |
| Transparency | Ultra-clear, HD level | Clear but less vivid |
| Impact Resistance | High (better anti-shatter) | Moderate |
| Durability | Excellent for long-term use | Decent, but less stable |
| Cost | Slightly higher | Lower cost |
| Finish Compatibility | Supports glossy, matte, privacy | Limited compatibility |
