Resistance overview
Polysulfone shows excellent resistance to Hydrochloric Acid across all 4 tested concentrations (1-5 %, 20 %, 35 %, concentrated) at 20 °C, making it a reliable choice for storage, transfer, and handling applications involving this chemical at any of the tested strengths. 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
Hydrochloric Acid is commonly encountered in laboratory work and chemical processing. Polysulfone (Polysulfone) is a thermoplastic typically used for tanks, piping, containers and liners. Because Hydrochloric Acid is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
Polysulfone can be used with confidence for Hydrochloric Acid 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. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.
Did you know?
When choosing between thermoplastics for Hydrochloric Acid service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

About Polysulfone
Polysulfone withstands hot water and steam. Ketones, esters and chlorinated and aromatic solvents attack it.
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.
