Ultra Clear Float Glass/Low iron glass

 

Adopting the advanced global low iron glass production technology, the production of ultra clear glass is completely automatic. Ultra clear glass also called low iron glass is a kind of exceeding clarity, 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.

 

Ultra clear glass/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.

 

Dimension of low iron glass/ultra clear glass is normally:

 

Thickness: 3-19mm, Width x Height: 12000x3300mm

 

Low Iron Solar Glass

Low Iron Solar Glass takes full advantages of the diffuse reflection of the pattern to decrease the light reflection, thus Low Iron Solar Glass has a very high solar transmittance at any angle incidence. Meanwhile, the low iron content of less than 120 ppm enables a very low solar absorbance by the glass itself, and on the contrary increases the transmittance. With the non-toxic chemical composition, low iron patterned solar glass completely conforms to the rigorous environmental requirement of Europe, USA and Japan. It is the ideal encapsulation material for solar panels (PV modules) and the flat solar thermal products.
