SCHOTT Xensation®
Chemical strengthened alumino-silicate glass

Xensation® is a chemically strengthened alumino-silicate glass that offers an outstanding level of mechanical impact and bending strength, as well as high resistance to scratches. This specialty glass has been designed to achieve strength performance levels ideally suited to tough applications – from smartphone to rugged displays to automotive applications to safety glazing.

Key-Benefits of Xensation® 3D

  • Extremely high impact and bending strength for thinner, sleeker and more touch sensitive solutions
  • High scratch resistance and tolerance for superior aesthetic appeal, durability, strength and reliability even after surface damage
  • Manifold combinations of CS and DoL at the highest levels
  • Easy to process and strengthen according to accepted industry standards
