Flat Polycarbonate Sight Glass

Polycarbonate is a group of thermoplastics that are easy to work with, mold and thermoform, and 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.

Polycarbonate is a group of thermoplastics that are easy to work with, mold and thermoform, and 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.

These sight glasses are mainly used in equipment that operates at low temperatures and where safety is sought in the event of breakage due to accidental impact.

They are supplied in round, rectangular, oblong, bored, conical shapes, etc. and in thicknesses from ¼” to 2″.
