Product overviewWe have developed series of sealing glass with different melting points. They can be used between 440℃to 980℃for glass-to-melt sealing, glass-to-ceramic sealing, silicon materials sealing and glass-to-glass sealing. Glass-sealed plug is one of the products made up of metallic shell and metallic pins bonded by a kind of special sealing glass melted at a high temperature. It has excellent performances of high temperature tolerance, high-pressure tolerance, high electronic resistance and good sealing property. It is applied to the satellite rocket separation, the unlock system of the solar panels when satellite launching and the ignition system of missile or spaceship.
