1.1mm 2.5mmTBorosilicate glass for Lampshade optical cutting glass by laser with round edge

High borosilicate glass (also known as hard glass), is processed by advanced technology, using the conductive characteristic in high temperature to internal heat glass to melt it .The thermal expansion coefficient is (3.3士0.1)x10-6/K, so some people also call it "borosilicate glass 3.3". It is a kind of special glass material that is of low inflation, high temperature resistant, high strength, high hardness, high transmittance and high chemical stability. For the excellent performance, it is widely used in solar power, chemical industry, pharmaceutical packaging, electric light source, craft decorations and other industries
