Frequently Asked Questions

Which materials resist Ammonium Nitrate at high concentrations?

The materials with an A rating (resistant) for Ammonium Nitrate at 20 °C are: PTFE, HDPE, PP, PVDF, PVC Rigid, EPDM, NBR, SS 316. These can generally be used in direct contact.

Does temperature affect chemical resistance to Ammonium Nitrate?

Yes. 3 of 14 tested materials show a worse rating at 50 °C than at 20 °C for Ammonium Nitrate. Materials affected include: HDPE, PVC Rigid, Acetal (POM).

Is PTFE safe for Ammonium Nitrate?

PTFE is rated A for Ammonium Nitrate at 20 °C. A rating of A means resistant, B means limited resistance, C means partly resistant, and D means not resistant.

Does concentration affect chemical resistance to Ammonium Nitrate?

Yes. Ammonium Nitrate is tested at 2 concentrations (10 %, saturated). Some materials change their rating depending on the concentration.

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.
