• Application: CHIYAN-M2’s 0.25~2.0mm thickness medium alumino-silicate glass has already been used in the market to meet a wide range of customers needs. Widely used in vehicle, consumer electronics cover plate, photovoltaic, industrial touch, smart home field;

• 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.
