Low Iron Glass is also called Ultra clear glass, Ultra clear glass is a kind of exceeding clarity and low iron glass, which is also called low iron glass, high transmittance glass. It is a new type of high grade glass that has high performance and multifunction, the light transmittance achieves above 91.5%, it has the character of glittering and translucent, elegant and graceful, which has the title of crystal prince in glass family.
Low Iron Glass also has all the processable performances that high quality float glass has, has predominant physical, mechanical and optical characters, so it can been processed as other high quality float glass. Incomparably predominant quality and performance make the ultra clear glass has wider application space and brighter market foreground.
