Frequently Asked Questions
Which materials resist Tartaric Acid at high concentrations?
The materials with an A rating (resistant) for Tartaric Acid at 20 °C are: PTFE, HDPE, PP, PVDF, PVC Rigid, Viton (FPM), NBR, SS 316. These can generally be used in direct contact.
Which materials should be avoided with Tartaric Acid?
Materials rated D (not resistant) for Tartaric Acid are: Aluminium, Nylon (PA). These should not be used in contact with Tartaric Acid.
Does temperature affect chemical resistance to Tartaric Acid?
Yes. 5 of 19 tested materials show a worse rating at 50 °C than at 20 °C for Tartaric Acid. Materials affected include: PVC Rigid, SS 316, SS 304, Polycarbonate, PVC Flexible.
Is PTFE safe for Tartaric Acid?
PTFE is rated A for Tartaric 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 Tartaric Acid?
Yes. Tartaric Acid is tested at 2 concentrations (aqueous, 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.
