An ultra-thin glass is a type of thin glass with thickness ranging from 0.1 to 1.2mm. This glass is majorly composed of materials, such as borosilicate, alumino-borosilicate, alkali-aluminosilicate, and soda lime, which can be chemically treated to enhance the properties and strength of the glass. An ultra-thin glass is used across various industries, such as consumer electronics, automotive, and biotechnology.
