Panasonic's Tempered Vacuum Insulated Glass
Panasonic Corporation has announced the
development of tempered vacuum insulated glass and another vacuum insulated
glass with transparent pillars for use in automatic door systems, refrigerator
and freezer show cases and windows of public facilities, exhibition showcases
aquariums and office buildings. The tempered vacuum insulated glass will be
released in the first half of the next fiscal year that starts in April
2020.Vacuum insulated glass is manufactured by vacuum-sealing two sheets of
glass with vacuum sealing material melted at high temperature, while tempered
glass generally drops in strength when it is heated at high temperature.
Panasonic newly developed its proprietary "Super-low-temperature sealing
material" and consequently achieved the sealing of tempered glass in a
temperature zone in which it does not drop in strength. The technology capable
of manufacturing both the float and the tempered vacuum insulated glass is
Panasonic's proprietary technology.
