Resistance overview
Polystyrene is not resistant (D) to Chloroform at 100 % 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
Chloroform is commonly encountered in coatings and paints and cleaning and degreasing. Polystyrene (Polystyrene) 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
Polystyrene is not recommended for use with Chloroform. 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 FEP, PTFE, PVDF instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
Polystyrene was first developed in the 1930s and remains one of the most widely used thermoplastics in chemical handling equipment.

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

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.
