Japan's Asahi Glass unveiled on Thursday Dragontrail, a new glass aimed at smartphones and tablet PCs that is about six times as tough as conventional soda-lime glass and should be better suited to the rough-and-tumble life to which portable gadgets are subjected.
The company also showed videos of tests it had done on the glass. It bent but didn't break under 60kgs of weight and resisted the shock of a hammer strike in the videos.
Tough glass doesn't just mean gadgets are less likely to suffer broken screens. Because the glass is tougher, manufacturers can get away with using thinner sheets and that helps products slim down and get lighter.
The glass will go up against Corning's Gorilla glass, which boasts similar properties and has proved a hit with portable gadget makers. It's already used in more than 225 mobile devices including cell phones, laptop and tablet PCs, and was recently selected by Sony for the front glass for its flat-panel LCD TVs, said Corning.
