Ultra Thin Glass UTG Glass For Thin HD Portable Folding Screen Laptop Notebook Computer
Product description
Ultra thin flexible glass (UTG) is a flexible and bendable glass material with a thickness of less than 100 microns, and unlike conventional rigid glass, it can be bent without thermal processing and under external force alone. This material is made by a special manufacturing process and has the characteristics of ultra-thin, wear resistance, high temperature resistance, corrosion resistance, high strength, high light transmission, bending and good resilience.
It can greatly improve the durability and scratch resistance of the screen, ensure that the phone remains smooth as a mirror after countless folds, and bring users a clearer and more delicate visual experience.

Technical Comparison
There are three main types of drawing for UTG: primary drawing, secondary drawing, and chemical thinning.
One-pull molding can produce ultra-thin glass substrate with double original glass surface, with ultra-high surface quality, through precise control of longitudinal and transverse pulling force, the glass can be directly drawn to a thickness of 0.1mm or less, and has a very uniform thickness; from the comparison of production cost, product quality, environmental protection, etc., a drawing system has obvious advantages, and with the amplification of the folding screen market, a drawing system will become the The mainstream of the market
Our company's research and development of the material formula are patented layout, and through the patent authorization, can provide intellectual property rights for the production and sale of protection.
