SCHOTT BOROFLOAT® 33:
BOROFLOAT® 33 is a high-quality borosilicate glass with excellent properties and a wide range of uses.
It is produced by the Schotjena Glass Company using the micro-float process and the latest technology. This technology produces borosilicate glass with uniform texture, which has a mirror-like excellent surface, extremely high surface flatness and good optical properties.
BOROFLOAT® 33 Basic Performance:
· Excellent light transmission, very low fluorescence intensity and high ultraviolet and infrared transmittance.
· Very low expansion coefficient, strong thermal shock resistance and long-term working temperature up to 450 ºC.
· Excellent chemical stability, high resistance to corrosion of water, strong acids, strong alkalis and organic substances.
· Excellent anti scratch effect, high hardness and density can be 20% lower than ordinary soda lime glass.
· Very low alkali content can be used as an excellent electrical insulator.

The same-sheet temperature difference (the performance of a piece of glass to with stand the temperature difference between the heating center and the cooler edge)
Test method: the area of about 25 × 25cm 2 glass plate is heated to a certain temperature, while its edges are kept at room temperature. The glass breakage rate due to thermal stress should be no more5%. Use before testing SIC 40-type coarse sandpaper polishes the glass plate to simulate extreme surface wear that may occur in use.

BOROFLOAT® 33
Some materials are excited by high-intensity high-frequency shortwave and have the property of releasing electromagnetic radiation. This property is called fluorescence. It is affected by the purity and structural characteristics of the material, but also depends on the single pulse energy, pulse frequency and the excitation wavelength of the radiation.
BOROFLOAT® 33 is a highly transparent glass that exhibits very weak fluorescence in the visible wavelength range.
