Due to its high technology content and high production difficulty, ultra-white glass is expensive, which is 5 to 10 times that of ordinary glass, but the cost is only 2-3 times that of ordinary glass, and it has a high added value. Ultra-white glass accounts for 20%-30% of the total cost of thin film batteries. At present, only a few companies in the world, such as PPG in the United States, Saint-Gobain in France, Pilkington in the United Kingdom, and Asahi Glass in Japan, have mastered the production technology of ultra-clear glass. Among them, PPG has the most mature technology. In order to ensure the relative monopoly on the market, these glass giants mostly adopt technical blockade means, do not transfer technology and adopt a limited production marketing model, which makes ultra-white glass have a high entry barrier in terms of technology and capital.
The high price and excellent quality make the ultra-white glass a symbol of the identity of the building. From the perspective of sales around the world, ultra-white glass is only used in high-end restaurants, urban landmarks, government financial projects, large-scale high-end exhibition venues, such as Beijing's Bird's Nest, Water Cube, Chinese History Museum, and the country. The famous theaters of the Grand Theatre, Shanghai Opera House, etc. all use ultra-white glass.
