Frequently Asked Questions

Which materials resist Copper Sulfate (Copper Vitriol) at high concentrations?

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

Which materials should be avoided with Copper Sulfate (Copper Vitriol)?

Materials rated D (not resistant) for Copper Sulfate (Copper Vitriol) are: Aluminium. These should not be used in contact with Copper Sulfate (Copper Vitriol).

Does temperature affect chemical resistance to Copper Sulfate (Copper Vitriol)?

Yes. 1 of 13 tested materials show a worse rating at 50 °C than at 20 °C for Copper Sulfate (Copper Vitriol). Materials affected include: PVC Rigid.

Is PTFE safe for Copper Sulfate (Copper Vitriol)?

PTFE is rated A for Copper Sulfate (Copper Vitriol) 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.
