Rating scale

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

Corrected and disputed values

Source values use the scale 1 (very good) to 4 (not resistant); 1 = A, 4 = D.

Frequently Asked Questions

Which materials resist Sulfuric Acid at high concentrations?

The materials with an A rating (resistant) for Sulfuric Acid at 20 °C are: PTFE, PVDF, Viton (FPM), SS 316, SS 304, FEP, ECTFE/ETFE. These can generally be used in direct contact.

Which materials should be avoided with Sulfuric Acid?

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

Does temperature affect chemical resistance to Sulfuric Acid?

Yes. 6 of 22 tested materials show a worse rating at 50 °C than at 20 °C for Sulfuric Acid. Materials affected include: HDPE, PP, PVC Rigid, SS 316, SS 304, LDPE.

Is PTFE safe for Sulfuric Acid?

PTFE is rated A for Sulfuric 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 Sulfuric Acid?

Yes. Sulfuric Acid is tested at 7 concentrations (1-6 %, 20 %, 40 %, 60 %, 80 %, 95 %, fuming). 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.
