0.03mm Ultra-Thin Flexible UTG Glass for Foldable Smartphone Displays with 7H Hardness and 300,000+ Bending Cycles
0.03mm ultra-thin flexible glass (UTG) is a revolutionary material that provides exceptional durability and optical clarity for foldable smartphone displays. Unlike conventional rigid glass, UTG can bend without thermal processing under external force alone, offering superior scratch resistance and visual performance.
- High mechanical strength with 7H pencil hardness
- Exceptional scratch resistance for long-term durability
- Supercritical water oxidation resistance
- Excellent flexibility with ≤1.5mm bend radius
- High transparency with ≥92% light transmittance
- Electrical insulation properties
- Smooth surface quality
- ≥300,000 bending cycles reliability
