Material comparison at 20 °C
Resistance overview
Polycarbonate shows very good resistance (A) to Mineral Oil 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
Mineral Oil is commonly encountered in oil and gas and lubrication systems. Polycarbonate (Polycarbonate) 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
Polycarbonate can be used with confidence for Mineral Oil 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?
In industrial practice, Polycarbonate components exposed to Mineral Oil are typically inspected for swelling, discoloration, or loss of mechanical strength as early indicators of chemical attack.

About Polycarbonate
Polycarbonate is attacked by alkalis, amines, ketones, esters and many organic solvents, and it stress-cracks under load in contact with them.

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.
