XXL Format Ultra-Thin Ultra-White Glass Substrates - Low Defect, High Yield

Here are multiple English product description options for ultra-thin ultra-clear aluminosilicate glass:

  • Engineered for premium displays and high-end devices, offering scratch resistance and 91.5% light transmittance."
  • At just 0.33mm thickness, our aerospace-grade aluminosilicate glass delivers military-standard impact resistance while maintaining 91.5%+ transparency for foldable displays."
  • Specially formulated with mid-alumina composition (4.5-8% Al₂O₃) for enhanced chemical durability. Ideal for harsh environments from smartphone cover glass to laboratory equipment."
  • Advanced low-iron manufacturing process achieves Fe2O3<0.01 color distortion for premium retail displays and museum-grade protective glazing. Available in 0.5-2.0mm configurations."
  • Combining 600MPa surface compression strength with 0.4mm slimness. The ultimate solution for curved automotive displays and wearable tech requiring durability and optical purity.

Key Technical Highlights:
- Ultra-thin : 0.25mm~2mm available
- High light transmission : >91%
- Aluminosilicate composition benefits
- Target applications (electronics/architecture/optics)

Standard Size:1300*1100mm (5th Generation)

Note: The size can be customized according to customer's needs.

Product Composition

Ultra Clear Medium Alumino-Silicate Glass achieves better stress and strain depth than ordinary soda-lime glass by increasing the Al₂O₃ content in the glass and increasing the ion exchange capacity.
