“BOROFLOAT® is very resistant to attack from
water, alkalis, acids and organic substances. This chemically resistant type of borosilicate glass
contains a high percentage of silica and a considerable amount of boric oxide. Exposure
of BOROFLOAT® to water and acids results in only small amounts of monovalent ions leaching out of the glass. This creates a
thin pore-free silica coating on the outer surface of the glass making it near
impermeable to further attack. Even over long periods of time at temperatures
above 100°C, BOROFLOAT® exceeds the chemical resistance of most
materials. BOROFLOAT’s high chemical resistance makes
it suitable for use in critical medical and scientific applications, such as
electrophoresis, slides, cover plates and scintillators.
BOROFLOAT®
has one of the lowest coefficients of thermal expansion for conventional glass
materials, this provides BOROFLOAT® with good thermal shock
resistance. Combined with a maximum long term use temperature of 450°C, which
makes BOROFLOAT® a good choice for applications requiring good
thermal stability.”
