Borosilicate 3.3 floated glass sheet is also called heat resistant glass, it is very clear, and have a very smooth surface. It is manufactured by a unique micro-float process. This technique provides exceptional flatness, high surface quality, and low microroughness. Borosilicate glass sheet is used in a wide range of applications.
Typical Applications
· Industrial optics for high working temperature
· Glass components for lighting
· Sight-glass windows
