Glass Discs with Good Thermal and Optical Properties
Glass discs, whose material can be soda-lime, borosilicate or quartz, have different sizes and applications. The difference of soda-lime, borosilicate and quartz is the different content of silicon dioxide. The more silicon dioxide contain, the glass disc is stronger in thermal and optical properties.
The diameter of our glass disc can be 5 mm to 1000 mm. The thickness can be 0.3 mm to 40 mm. Compared with other factory products, our glass discs surface is polished and no bubble and edge is exact round and polished. What's more, Our glass discs can work in very high temperature as well as acid and alkali environment. In addition, as optical glass, our glass discs light transmittance can reach 93%.
With good thermal, mechanical and optical properties, the glass discs are widely used in instruments, LED lights, optical industry and so on.
Four pieces of glass discs are on the ground and they are all bright, smooth and polished.
GD-1: Our glass discs can be as thin as 0.3 mm and there is no bubble in them.One piece of glass disc stands on the ground.
GD-2: Our thin glass discs have good optical properties and can also resist acid and alkali.
