Asahi Glass has made glass that is 100 microns thick

AGC (Asahi Glass Company) has developed 100 microns (0.1 mm)-thin sheet glass manufactured using a float process for use in next-generation displays, lighting, and touch panel screens. AGC claims it to be the world’s thinnest.



This is the previous 280 micron thick soda-lime glass

Only in April the company announced glass sheets of 0.28 mm thick soda-lime glass substrate for touchscreens. Soda-lime glass is composed mainly of silicon dioxide, sodium oxide and calcium oxide, and is used widely in construction, automotives and many types of electronic devices.

The 0.1 mm sheets are alkali-free glass, composed mainly of silicon dioxide, boron oxide and aluminum oxide, is free of alkaline elements such as sodium and potassium, and is used widely as substrates for TFT-LCD and OLED.

Thin sheet glass is expected to be used in such products due to its flexible shaping and light weight, as well as basic characteristics of glass such as transparency, electrical insulation and resistance to heat, chemicals and gases.

* The float process is a glass-manufacturing method in which glass is floated over molten metal for the efficient production of highly uniform glass.
