Frequently Asked Questions

Which materials resist Succinic Acid at high concentrations?

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

Does temperature affect chemical resistance to Succinic Acid?

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

Is PTFE safe for Succinic Acid?

PTFE is rated A for Succinic 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 Succinic Acid?

Yes. Succinic Acid is tested at 2 concentrations (50 %, 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.
