SCHOTT Xensation^® 3D
Chemical strengthened lithium alumino-silicate cover glass for tough applications – from smartphone to safety glazing

Key-Benefits

Outstanding results in set drop performance for very high survival likelihhod after smartphone drops
Extremely high impact and bending strength for thinner, sleeker and more touch sensitive solutions
High scratch and wear resistance for superior aesthetic appeal, durability, strength and reliability even after surface damage
Thermal bending at similar temperatures to soda-lime glass
Manifold combinations of CS and DoL possible
