Sealing glass

Sealing glass is crucial in the encapsulation structure of metal substrates and metal pins, offering hermetic insulation. This specialized glass is used for airtight sealing, ensuring robust electrical insulation and protection in various applications, including electronic components, sensor packaging, and high-temperature environments. Its excellent sealing properties make it ideal for use in industries requiring reliable hermetic seals and superior insulation performance.
