Frequently Asked Questions
Which materials resist Sodium Bisulfate at high concentrations?
The materials with an A rating (resistant) for Sodium Bisulfate at 20 °C are: PTFE, HDPE, PP, PVDF, PVC Rigid, EPDM, Viton (FPM), NBR. These can generally be used in direct contact.
Which materials should be avoided with Sodium Bisulfate?
Materials rated D (not resistant) for Sodium Bisulfate are: Nylon (PA). These should not be used in contact with Sodium Bisulfate.
Does temperature affect chemical resistance to Sodium Bisulfate?
Yes. 4 of 13 tested materials show a worse rating at 50 °C than at 20 °C for Sodium Bisulfate. Materials affected include: PVC Rigid, NBR, SS 304, Aluminium.
Is PTFE safe for Sodium Bisulfate?
PTFE is rated A for Sodium Bisulfate 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 Sodium Bisulfate?
Yes. Sodium Bisulfate is tested at 2 concentrations (10 %, any concentration). 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.
