Borosilicate Floated 3.3 Glass Sheet: Clear, Stable Glass for Demanding Applications

What Is Borosilicate Floated 3.3 Glass Sheet?

Borosilicate floated 3.3 glass sheet is a flat glass made from borosilicate glass with a low coefficient of thermal expansion. It is manufactured using a float process, which provides a smooth, flat surface and good optical quality.

This product is also called borosilicate 3.3 glass sheet, borosilicate glass sheet, or borosilicate float glass. It is commonly selected when ordinary soda-lime glass cannot provide sufficient thermal resistance or dimensional stability.

Key Features

· High thermal resistance with good resistance to sudden temperature changes

· Low thermal expansion, helping reduce thermal stress

· Smooth and flat surface suitable for precision applications

· Good chemical resistance

· Good light transmission and surface quality

· Can be cut, drilled, ground, polished, tempered, or processed according to application requirements

Where Is It Used?

Borosilicate floated 3.3 glass sheet is used in applications where both flatness and thermal performance are important.

Typical uses include:

· Laboratory equipment and scientific instruments

· High-temperature observation windows

· Industrial equipment and inspection windows

· Lighting and optical applications

· Solar and thermal equipment

· Chemical processing equipment

· Protective covers and instrument panels

For applications involving heating, cooling, or frequent temperature changes, the low thermal expansion of borosilicate 3.3 glass can be an important advantage over conventional flat glass.

Borosilicate 3.3 Glass Sheet vs. Ordinary Float Glass

The main difference is the glass composition and thermal behavior. Borosilicate 3.3 glass has a much lower thermal expansion coefficient than standard soda-lime float glass, making it more suitable for applications exposed to elevated temperatures or thermal cycling.

However, the correct glass should always be selected according to the actual temperature, dimensions, installation method, and mechanical requirements of the equipment.
