A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.

Frequently Asked Questions

Which materials resist Magnesium Bromide at high concentrations?

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

Does temperature affect chemical resistance to Magnesium Bromide?

For Magnesium Bromide, all tested materials maintain the same rating at both 20 °C and 50 °C.

Is PTFE safe for Magnesium Bromide?

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

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.
