Frequently Asked Questions
Which materials resist Styrene at high concentrations?
The materials with an A rating (resistant) for Styrene at 20 °C are: PTFE, SS 316, SS 304, Aluminium, FEP, Nylon (PA), Acetal (POM), PETG. These can generally be used in direct contact.
Which materials should be avoided with Styrene?
Materials rated D (not resistant) for Styrene are: HDPE, PVC Rigid, EPDM, NBR, Polycarbonate, PVC Flexible, PMP. These should not be used in contact with Styrene.
Does temperature affect chemical resistance to Styrene?
Yes. 2 of 15 tested materials show a worse rating at 50 °C than at 20 °C for Styrene. Materials affected include: PP, LDPE.
Is PTFE safe for Styrene?
PTFE is rated A for Styrene 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.
