Material comparison at 20 °C
Resistance overview
Polysulfone shows good but limited resistance (B) to Adipic Acid at saturated 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
Adipic Acid is commonly encountered in surface cleaning and metal finishing. Polysulfone (Polysulfone) 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
Polysulfone is suitable for use with Adipic Acid 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, Polycarbonate instead, which are rated A for this chemical.
Did you know?
Polysulfone was first developed in the 1960s and remains one of the most widely used thermoplastics in chemical handling equipment.

About Polysulfone
Polysulfone withstands hot water and steam. Ketones, esters and chlorinated and aromatic solvents attack it.
Rating scale
- A very good resistance
- B good resistance
- C limited resistance
- D not resistant
- – no data
- K no general statement possible
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.
