4.0 borosilicate float glass is produced by the technology of float glass making.main ingrddients of this float glass are sodium oxide(Na2o),boron high content. For example,boron:12.5-13.5%,silicon 78-80%.In this case,this special glass are called borosilicate float glass.The feature of the glass is that it has small thermal expansion coefficient,good thermal stability,chemical durability and electrical property.Therefore,borosilicate float glass'chemical resistant,heat resistant and mechamical property are excellent,moreover,the glass could use in high temperature and has strong  ,borosilicate glass is called heat resistant glass as well. it is a special flameproof glass.
