Core Material & Strengthening (Glass & Tempering)
Mar 31, 2026
The industry is dominated by Aluminosilicate (e.g., Corning Gorilla, AGC Dragontrail) due to its high surface compressive stress.
Chemical Strengthening (ion-exchange in KNO₃ bath) is the standard, measured by DOL (Depth of Layer) and CS (Compressive Stress).
Unlike thermal tempering, this allows for sub-0.5mm ultra-thin substrates essential for foldables and wearables.
