Frequently Asked Questions
Which materials resist Diethyl Ketone at high concentrations?
The materials with an A rating (resistant) for Diethyl Ketone at 20 °C are: PTFE, SS 316, SS 304, Aluminium, FEP, Acetal (POM). These can generally be used in direct contact.
Which materials should be avoided with Diethyl Ketone?
Materials rated D (not resistant) for Diethyl Ketone are: PVC Rigid, Viton (FPM), NBR, Polycarbonate, Polystyrene, Polysulfone, PETG, SAN. These should not be used in contact with Diethyl Ketone.
Does temperature affect chemical resistance to Diethyl Ketone?
Yes. 3 of 12 tested materials show a worse rating at 50 °C than at 20 °C for Diethyl Ketone. Materials affected include: LDPE, ECTFE/ETFE, PMP.
Is PTFE safe for Diethyl Ketone?
PTFE is rated A for Diethyl Ketone 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.
