Resistance overview

Polycarbonate shows good but limited resistance (B) to Lithium Bromide at 20 °C. The material can be used in contact with this chemical, but minor effects such as slight swelling or a small reduction in mechanical properties may occur over extended exposure periods. Regular inspection of components in service is advisable. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.

Application context

Lithium Bromide is commonly encountered in waste treatment and water disinfection. Polycarbonate (Polycarbonate) is a thermoplastic typically used for tanks, piping, containers and liners. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.

Practical recommendation

Polycarbonate is suitable for use with Lithium Bromide under normal conditions, but some minor effects on the material are expected over time. Periodic monitoring for swelling, softening, or weight change is recommended, especially for long-service components. For safety-critical or long-life applications, consider HDPE, LDPE, PETG instead, which are rated A for this chemical.

Did you know?

Polycarbonate was first developed in the 1950s and remains one of the most widely used thermoplastics in chemical handling equipment.

About Polycarbonate

Polycarbonate is attacked by alkalis, amines, ketones, esters and many organic solvents, and it stress-cracks under load in contact with them.

Rating scale

A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.

About this data

The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.

A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
