Resistance overview

Polystyrene is not resistant (D) to Bromine and should not be used in direct contact. The chemical is expected to cause rapid degradation, which can include dissolution, cracking, severe swelling, or complete structural failure of the material.

Application context

Bromine is commonly encountered in chemical processing and bleaching. Polystyrene (Polystyrene) is a thermoplastic typically used for tanks, piping, containers and liners. Because Bromine is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.

Practical recommendation

Polystyrene is not recommended for use with Bromine. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using ECTFE/ETFE, FEP, PTFE instead, which are rated A for this chemical and offer reliable long-term performance.

Did you know?

The ratings shown here apply to pure Bromine in contact with the base thermoplastic. In real-world applications, additives, pigments, and fillers in the material can shift resistance in either direction.

About Polystyrene

Polystyrene is attacked by most organic solvents, including ketones, esters, aromatic and chlorinated hydrocarbons. It is used for dilute aqueous solutions.

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.
