A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
Frequently Asked Questions
Which materials resist Cresol at high concentrations?
The materials with an A rating (resistant) for Cresol at 20 °C are: PTFE, PVDF, Viton (FPM), SS 316, SS 304, Aluminium, FEP, ECTFE/ETFE. These can generally be used in direct contact.
Which materials should be avoided with Cresol?
Materials rated D (not resistant) for Cresol are: PVC Rigid, EPDM, NBR, LDPE, Nylon (PA), Acetal (POM), Polycarbonate, PVC Flexible. These should not be used in contact with Cresol.
Does temperature affect chemical resistance to Cresol?
Yes. 4 of 20 tested materials show a worse rating at 50 °C than at 20 °C for Cresol. Materials affected include: HDPE, PP, ECTFE/ETFE, SAN.
Is PTFE safe for Cresol?
PTFE is rated A for Cresol 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.
