Polycarbonate Level Gauge Glass Tube

Polycarbonate is a group of thermoplastics that are easy to work with, mold and thermoform. They are widely used in modern manufacturing.

The name “polycarbonate” is based on the fact that they are polymers that have functional groups linked by carbonate groups in a long molecular chain.

Description

Polycarbonate is a group of thermoplastics that are easy to work with, mold and thermoform. They are widely used in modern manufacturing.

The name “polycarbonate” is based on the fact that they are polymers that have functional groups linked by carbonate groups in a long molecular chain.

Because this material is approved by the FDA (USA Food and Drug Administration), it is commonly used in the food, pharmaceutical and chemical industries. In order to ensure proper sealing and facilitate assembly, all cuts are squared and polished.

Tubular sight glasses are used instead of polycarbonate sight glasses when greater impact and chipping resistance is sought, as well as when greater flexibility is desired for the sight glass.
