Borosilicate glass tube and Polycarbonate tube difference used in industry sight glass

When it comes to industry sight glasses, the choice between borosilicate glass tubes and polycarbonate tubes can make a significant impact on the performance and durability of the equipment. Let's explore the key differences between these two materials.

What is Borosilicate Glass Tube?

Borosilicate glass is a type of glass that contains boron trioxide which allows for a low coefficient of thermal expansion. This means that borosilicate glass can withstand high temperatures and sudden changes in temperature without cracking or shattering. It is also highly resistant to chemical corrosion, making it an ideal choice for sight glasses in industrial applications.

What is Polycarbonate Tube?

Polycarbonate is a transparent thermoplastic that is known for its high impact resistance and toughness. While polycarbonate tubes are lightweight and durable, they are not as resistant to high temperatures or chemical corrosion as borosilicate glass tubes. This makes them more suitable for applications where impact resistance is a priority over temperature and chemical resistance.

Key Differences

One of the main differences between borosilicate glass tubes and polycarbonate tubes is their resistance to temperature and chemical corrosion. Borosilicate glass tubes can withstand high temperatures and harsh chemicals, making them suitable for a wide range of industrial applications. On the other hand, polycarbonate tubes are better suited for applications where impact resistance is crucial, but temperature and chemical resistance are less of a concern.

Another key difference is the clarity of the material. Borosilicate glass offers exceptional clarity, allowing for easy visibility of the contents in the sight glass. Polycarbonate, while transparent, may not offer the same level of clarity as borosilicate glass.

Ultimately, the choice between borosilicate glass tubes and polycarbonate tubes will depend on the specific requirements of the application. By understanding the differences between these two materials, industry professionals can make an informed decision that will optimize the performance and longevity of their sight glass equipment.
