Frequently Asked Questions

Which materials resist Sodium Acetate at high concentrations?

The materials with an A rating (resistant) for Sodium Acetate at 20 °C are: PTFE, HDPE, PP, PVDF, EPDM, SS 316, SS 304, Aluminium. These can generally be used in direct contact.

Does temperature affect chemical resistance to Sodium Acetate?

Yes. 2 of 18 tested materials show a worse rating at 50 °C than at 20 °C for Sodium Acetate. Materials affected include: PVC Rigid, Polycarbonate.

Is PTFE safe for Sodium Acetate?

PTFE is rated A for Sodium Acetate 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.
