1. How Tempered Glass is Made
-
The glass is heated to high temperatures and then rapidly cooled, a process called tempering.
-
This process creates internal stress, making the glass 5–6 times stronger than normal glass.
-
If broken, it shatters into small, blunt pieces instead of sharp shards, reducing injury risk.
2. Key Features of Tempered Glass
-
Scratch Resistance: Most tempered glass has a 9H hardness rating, protecting against keys, coins, and daily wear.
-
Clarity: Maintains high transparency, preserving screen brightness and color accuracy.
-
Touch Sensitivity: Thin and smooth, ensuring responsive touch performance.
-
Oleophobic Coating: Resists fingerprints, smudges, and minor oil stains.

-
Protects the mobile screen from scratches and minor impacts.

Prevents full screen damage during accidental drops.
-
Keeps your phone looking new and clean for longer.

Easy to replace if cracked or damaged, without affecting the original screen.
4. Difference From Plastic Screen Protectors

Tempered glass is real heat-treated glass, while plastic films are flexible and less durable.

Offers better protection, clarity, and touch experience than plastic alternatives.
