Rating scale

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 Heating Oil at high concentrations?

The materials with an A rating (resistant) for Heating Oil at 20 °C are: PTFE, PP, PVDF, PVC Rigid, Viton (FPM), NBR, SS 316, SS 304. These can generally be used in direct contact.

Which materials should be avoided with Heating Oil?

Materials rated D (not resistant) for Heating Oil are: EPDM. These should not be used in contact with Heating Oil.

Does temperature affect chemical resistance to Heating Oil?

Yes. 5 of 21 tested materials show a worse rating at 50 °C than at 20 °C for Heating Oil. Materials affected include: PP, LDPE, Polystyrene, Polysulfone, PMP.

Is PTFE safe for Heating Oil?

PTFE is rated A for Heating Oil 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.
