Resistance overview

SAN shows very good resistance (A) to Ammonium Sulfate at saturated 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

Ammonium Sulfate is commonly encountered in chemical storage and de-icing. SAN (Styrene-acrylonitrile) 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

No resistance data is available for SAN in contact with Ammonium Sulfate. Before using this combination, consult the material manufacturer or conduct independent testing.

Did you know?

Chemical resistance testing according to DIN and ISO standards typically evaluates weight change, dimensional change, and retention of tensile strength after immersion.

About SAN

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