BOROFLOAT®
Thicknesses and dimensions
Thermal
The CTE of BOROFLOAT® 33 is 3 times lower than the CTE of Soda-lime glass.
Optical
Inherent fluorescence
Chemical
Quantity of Na2O released from BOROFLOAT® 33 compared tosoda-lime glass depending on the temperature after 16 hours.
Compared to soda-lime glass, BOROFLOAT® 33 has a significantly higher hydrolytic resistance, because the number of sodium ions in the glass network is significantly lower with BOROFLOAT® 33. The few sodium ions are also more strongly bound.
