The company can provide ST5816, ST5817, GD6 and other sealing glass. Compared with traditional sealing glass, our sealing glass provides reliable sealing protection for products and it has the characteristics of high temperature and pressure resistance, heat shock resistance, chemical resistance, high electrical insulation and excellent optical properties. It is widely used in electronic technology, laser infrared technology, electric light source, high-energy physics and aerospace, energy industry, automotive industry and other packaging fields.
The packaging design and technical specifications of components are different in different application; our company can develop and produce according to the product performance required by customers.
The supply form is generally strips; it also can be customized upon request of customers.
ST5816 and ST5817 belong to high temperature sealing glass, in which ST5817 belongs to alkali free aluminosilicate glass. The glass does not contain alkali metal oxide, and the operating temperature is higher than ST5816. It is mainly used for high temperature welding and encapsulation of electronic components.
