Material comparison at 20 °C
Resistance overview
SAN shows very good resistance (A) to White Spirit at liquid at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. However, at 50 °C the resistance rating drops, indicating that temperature must be factored into the design. For heated applications, additional testing under actual service conditions is strongly recommended.
Application context
White Spirit is commonly encountered in fuel storage and transfer and automotive. SAN (Styrene-acrylonitrile) 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
SAN can be used with confidence for White Spirit containment and handling. The A rating indicates that the material shows no significant change in weight, dimensions, or mechanical properties after prolonged contact under test conditions. At elevated temperatures (50 °C), some reduction in resistance occurs, so periodic inspection is advisable for heated applications. Always verify performance under actual operating conditions before committing to a design.
Did you know?
When choosing between thermoplastics for White Spirit service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

About SAN
Styrene-acrylonitrile resists oils and dilute acids better than polystyrene, but ketones, esters and aromatic and chlorinated solvents still attack it.

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.
