"Chemical strengthened glass" is glass that has been immersed in molten salt and undergoes ion exchange to form a layer of compressive stress on its surface. There are two methods for strengthening glass: air cooling and chemical strengthening. The strengthening of glass improves its properties, which are weak in tension, by generating compressive stress on the glass surface. As a result, the strength can be increased to more than five times that of ordinary glass. [Features] - Strengthening is possible even with thin glass - There is almost no deformation due to strengthening - Can be strengthened for irregular shapes and bent glass - Strengthening is possible for thin glass sheets up to 0.4mm thick - No deformation occurs, resulting in high flatness and dimensional accuracy *For more details, please refer to the PDF document or feel free to contact us.
