Frequently Asked Questions

Which materials resist Sodium Peroxide at high concentrations?

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

Which materials should be avoided with Sodium Peroxide?

Materials rated D (not resistant) for Sodium Peroxide are: Aluminium, Nylon (PA), Acetal (POM), PETG. These should not be used in contact with Sodium Peroxide.

Does temperature affect chemical resistance to Sodium Peroxide?

Yes. 1 of 9 tested materials show a worse rating at 50 °C than at 20 °C for Sodium Peroxide. Materials affected include: LDPE.

Is PTFE safe for Sodium Peroxide?

PTFE is rated A for Sodium Peroxide 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 Sodium Peroxide?

Yes. Sodium Peroxide is tested at 2 concentrations (10 %, saturated). 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.
