CHIYAN High Alumino-Silicate Glass Pro for Vehicle Display Car Mounted Cover
High Alumino-Silicate Glass (CHIYAN-H1 PRO) is a float alkali aluminosilicate ultra-thin flat glass.
Based on a specially designed formula, this glass can achieve ultra-high CS and the same DOL as conventional high-alumina glass based on chemical strengthening, which greatly improves the mechanical strength performance of the product. At the same time, this product has excellent Vickers hardness after strengthening, giving it better scratch resistance. The excellent characteristics of Chiyan H1 PRO glass can help reduce product failure rates and improve customer experience.
Features:
Application: CHIYAN-H1 PRO’s 0.3~6.0mm thickness high alumino-silicate glass has already been used in the market to meet a wide range of customers needs. Widely used in High-end Consumer Electronics Device Display Cover, Glass Substrate for display, Vehicle Display, Car Windows etc fields;
Regular Thickness:0.3mm~6mm
Standard Size:1300*1100mm (5th Generation)
Note: The size can be customized according to customer's needs.
Product Composition
High 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
Storage Conditions: Temperature ≤30℃, humidity ≤65% (no condensation), shelf life is 6 months from the date of delivery.
High Alumino-Silicate Glass (CHIYAN-H1 PRO) is adopted Float Glass Process.
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:
