Glass Sealing Preforms
Over 300 glass compositions are available
from GBC. Thermal expansions are available
over a range from 32 to 130 x 10-7
in/in/ºC. Stringent batch controls
provide the highest degree of dependability.
The preformed frames, rings, and solids
introduce a finite amount of sealing glass
which can be shaker-loaded into sealing
fixtures. Research and development is
continuing to provide a wide range of
expansion coefficients in low temperature
sealing glasses.
