Aluminosilicate glass original sheet for Smart Display Screen Cover Toughened Glass
Ultra Clear super white Medium Alumino-Silicate electronic float glass original pieces(CHIYAN-M2) is an eco-friendly ultra-thin alumino-silicate glass with certain strength.
Cover glass is a critical part of a capacitive touch screen, and its attributes greatly influence the screen's performance. Here are key considerations for cover glass:
Glass Thickness: Choosing the appropriate glass thickness is of utmost importance. It's often evaluated for its resistance to vandalism, making it ideal for public and industrial settings. The glass comes in different thicknesses to achieve varying IK degrees, ensuring it can withstand different levels of impact. This includes options like chemical toughened glass and physically toughened glass, each suited for different applications and durability requirements.
Features:
High Impact Resistance
High Scratch Resistance
High Flexibility
High Bending Strength Resistance

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.

Packaging Diagram
Float glass is made by heating raw materials—silica sand, limestone, soda ash, and magnesium in a furnace. When melted, it’s then spread out over a sizable bed of molten tin. As it moves along rollers in the annealing oven during a controlled cooling process, this mixture slowly solidifies over the molten tin. From this point, a single, continuous smooth ribbon of glass emerges as below picture showed:
Storage
