Resistance overview

Polystyrene is not resistant (D) to White Spirit at liquid 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

White Spirit is commonly encountered in automotive and fuel storage and transfer. Polystyrene (Polystyrene) is a thermoplastic typically used for tanks, piping, containers and liners. Since White Spirit is flammable, material selection must also consider the risk of static charge buildup and the need for proper grounding in storage and transfer systems.

Practical recommendation

Polystyrene is not recommended for use with White Spirit. 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 Nylon (PA), PETG, Acetal (POM) 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.

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.
