Material comparison at 20 °C
Resistance overview
Polysulfone shows very good resistance (A) to Zinc Nitrate at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. 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
Zinc Nitrate is commonly encountered in de-icing and food processing. Polysulfone (Polysulfone) is a thermoplastic typically used for tanks, piping, containers and liners. Because Zinc Nitrate 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 Zinc Nitrate 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?
The chemical resistance of Polysulfone depends not only on the chemical concentration but also on exposure time, mechanical stress, and the presence of other chemicals in the mixture.

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