Product Description

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
• Glass covers for sensors
• Laboratory glassware
• Chemical, pharmaceutical, food and drink industries
• Window for oven and furnace
