Product Detailed

Optical special glass

Borosilicate float glass is produced by the technology of float glass production.Main ingredients of this float glass are sodium oxide Na2O,boron oxide(B2O3),silicon dioxide SiO2.Of these ingredients,boron and silicon have high content.The feature of this glass is that it has small thermal expansion coefficient of 3.3,good thermal stability ,chemical durability and electrical property.Moreover,this glass could use in high temperature and has strong hardness,and have the function of uvioresistant.The light transmission are above 90%.Borosilicate float glass has wide application in lighting,chemical,fireplace,steel,food-machinery,solar energy,optical,semi conductor technology,petroleum and sight glass under high temperature and pressure.Also we can deep-process them into round,rectangular,heat-bending or holes-punching.We can provide size of 1200*650mm,1180*850 with the thickness of 1.5,2,2.25,2.75,3,3.3,4,5,6,8,10,12,15,20,25,30,50mm.Also we can print them with different colour.
