China makes world’s thinnest phone glass

China Daily - - CHINA - Zhang Yangfei contributed to this story.

China has pro­duced the world’s thinnest float glass — the type most of­ten used on cell­phone touch screens and sim­i­lar de­vices — with im­proved light trans­mit­tance and flex­i­bil­ity.

Pro­duced by the Bengbu De­sign and Re­search In­sti­tute for Glass In­dus­try in An­hui prov­ince, the ul­tra­thin float glass, mea­sur­ing just 0.12 mil­lime­ters thick, or slightly thicker than a sheet of printer pa­per, has beaten the pre­vi­ous record of 0.15 mm set ear­lier by the in­sti­tute.

It also can with­stand the im­pact of a 55-gram steel ball fall­ing from a height of 1 meter. All of this is “a very re­mark­able achieve­ment world­wide for 0.12 mm glass”, said Cao Xin, deputy di­rec­tor of the in­sti­tute’s State key lab­o­ra­tory.

Ren Hong­can, a gen­eral man­ager on the pro­duc­tion line, said the sur­face area of the glass may be lim­ited be­cause of its thin­ness, and de­vel­op­ers are work­ing on how to en­large it.

Ul­tra­thin float glass plays a crit­i­cal role in mak­ing elec­tronic de­vices lighter and smaller, Ren said.

“The price of China’s touch screens is sure to go down, which will surely ben­e­fit the en­tire elec­tri­cal de­vice mar­ket,” he said.

The Bengbu in­sti­tute started re­search­ing and man­u­fac­tur­ing float glass in 2013. It first pro­duced 0.33 mm glass in 2014 and man­aged to re­duce the thick­ness to 0.15 mm two years later. The 0.12 mm glass has yet to hit the mar­ket.

“Once we have the thinnest float glass in the world, all the other de­vices also need to be de­vel­oped to match such a thin stan­dard,” Ren said. “But we are ready to launch it when­ever there’s need.”

Now, in­stead of go­ing for thin­ner glass, the com­pany is work­ing to­ward better qual­ity and sta­bil­ity.
