Schott BOROFLOAT® Borosilicate Float Glass
Categories: Ceramic; Glass; Optical; Oxide; Silicon Oxide

Material Notes: This is a highly chemically resistant borosilicate glass with a low thermal expansion. BOROFLOAT® replaced TEMPAX®, a drawn flat borosilicate glass for Schott. The high quality resulting from the float glass process opens up new applications for borosilicate flat glass in laboratories, chemical process plants and in the home appliance and lighting industries.

BOROFLOAT® flat glass is highly resistant to water; neutral, acidic and saline solutions; as well as to chlorine, bromine, iodine and organic substances. Even over long periods of time and at high temperatures that exceed 100°C, BOROFLOAT® exceeds the chemical resistance of most metals and other materials.
