The sudden rise of ultra-thin glass boosted the upgrading of the industry

in 2015, China's flat glass industry moved forward in an extremely difficult urban environment. From January to November, the output of 120 ° flat diamond cone glass was 693.38 million weight boxes, a year-on-year decrease of 7. 9%。 In such a depressed situation, ultra-thin glass products have sprung up, and exciting good news has been coming from time to time, bringing a ray of light to the glass industry

China's ultra-thin glass is developing rapidly.

ultra thin glass refers to the thickness of 0. 1~1。 1mm glass. Because of its ultra-thin thickness, it has many special properties. It is mainly used for LCD panel substrate. After the rise of touch screen (TP), ultra-thin glass is also used for touch screen cover plate and touch screen sensor substrate. The overall development of China's ultra-thin glass in 2015 is commendable

in 2015, the demand for ultra-thin glass in China was 164.92 million m2, with a year-on-year increase of 25. 51%, accounting for 30% of the global demand for ultra-thin glass. 27%。 The demand for TFT-LCD glass substrate was 98.25 million m2, a year-on-year increase of 28. 8%, accounting for 22% of the global demand for TFT-LCD glass substrates. 14%; The demand for cover glass was 41.54 million m2, a year-on-year increase of 26. 72%; The demand for ITO glass substrates was 25.13 million m2, a year-on-year increase of 15%

in 2015, China's ultra-thin glass production capacity was 137.45 million m2, with a year-on-year increase of 20. 97%。 The production capacity of soda lime silica ultra-thin glass was 100.6 million m2, an increase of 11% year on year. 22%; Alkali free glass substrate was 19.35 million m2, with a year-on-year increase of 13. 69%; The production capacity of high aluminum cover glass is 17.5 million m2, achieving a breakthrough

in 2015, the production capacity of China's ultra-thin glass industry not only increased significantly, but the product variety, especially the product thickness, exceeded 0. 55mm threshold, directly towards 0. 2mm, gradually in line with international standards. In 2015, 5 enterprises achieved 0. For the production or industrialization of ultra-thin glass with a thickness of less than 33mm, it is worth mentioning that on October 30, the 150t/d aluminum silicon glass production line of Sichuan Xuhong optoelectronics Co., Ltd. successfully produced 0. 33mm aluminum silicon glass
