Frequently Asked Questions

Which materials resist Hydrobromic Acid at high concentrations?

The materials with an A rating (resistant) for Hydrobromic Acid at 20 °C are: PTFE, HDPE, PP, PVDF, PVC Rigid, Viton (FPM), LDPE, FEP. These can generally be used in direct contact.

Which materials should be avoided with Hydrobromic Acid?

Materials rated D (not resistant) for Hydrobromic Acid are: NBR, SS 316, SS 304, Aluminium, Nylon (PA), Acetal (POM), Polycarbonate, Polystyrene. These should not be used in contact with Hydrobromic Acid.

Does temperature affect chemical resistance to Hydrobromic Acid?

Yes. 2 of 15 tested materials show a worse rating at 50 °C than at 20 °C for Hydrobromic Acid. Materials affected include: PP, LDPE.

Is PTFE safe for Hydrobromic Acid?

PTFE is rated A for Hydrobromic Acid 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 Hydrobromic Acid?

Yes. Hydrobromic Acid is tested at 3 concentrations (40 %, 50 %, dilute). 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.
