CHIYAN Ultra Thin Flexible Glass for Foldable Smartphone
Ulta Thin Glass (CHIYAN-U1) is an ultra-thin flexible glass product exclusively developed by CHIYAN and manufactured using a one-step drawing and forming process. It has excellent scratch resistance, high strength, water and oxygen resistance, etc.
Foldable screens use ultra-thin glass that can be folded hundreds of thousands of times without breaking. Ultra-thin glass is also clearer, more scratch-resistant, and can take more pressure than plastic.
Characteristics:
Excellent optical properties
Super bending performanc
Good scratch resistance
CHIYAN-U1’s 0.03mm t~0.15mm thickness high alumino-silicate glass has already been used in the market to meet a wide range of customers needs.
Application:
It can be used in folding mobile phones, portable devices, and wearable devices and Display, Vehicle Display, Hight-tech Equipment and other fields.
Regular Thickness:
0.03mm,0.05mm,0.07mm,0.1mm, 0.15mm
Standard Size:400*500mm
Note: The size can be customized according to customer's needs.
