Frequently Asked Questions

Which materials resist Chloroacetic Acid at high concentrations?

The materials with an A rating (resistant) for Chloroacetic Acid at 20 °C are: PTFE, HDPE, PP, LDPE, FEP, ECTFE/ETFE, PMP. These can generally be used in direct contact.

Which materials should be avoided with Chloroacetic Acid?

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

Does temperature affect chemical resistance to Chloroacetic Acid?

Yes. 6 of 21 tested materials show a worse rating at 50 °C than at 20 °C for Chloroacetic Acid. Materials affected include: PP, PVC Rigid, Polycarbonate, Polystyrene, PMP, SAN.

Is PTFE safe for Chloroacetic Acid?

PTFE is rated A for Chloroacetic 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 Chloroacetic Acid?

Yes. Chloroacetic Acid is tested at 2 concentrations (50 %, concentration not stated). 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.
