Resistance overview

Nylon (PA) maintains a consistent rating of D across all 2 tested concentrations (10 %, saturated) of Sodium Peroxide at 20 °C. The fact that the rating does not change with concentration within the tested range simplifies material selection, though the boundary conditions beyond this range remain untested. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.

Application context

Sodium Peroxide is commonly encountered in chemical processing and bleaching. Nylon (PA) (Polyamide (nylon)) is a thermoplastic typically used for tanks, piping, containers and liners. Because Sodium Peroxide is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.

Practical recommendation

Nylon (PA) is not recommended for use with Sodium Peroxide. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using LDPE, PVC Rigid, PTFE instead, which are rated A for this chemical and offer reliable long-term performance.

Did you know?

The ratings shown here apply to pure Sodium Peroxide in contact with the base thermoplastic. In real-world applications, additives, pigments, and fillers in the material can shift resistance in either direction.

About Nylon (PA)

Polyamide (nylon) resists fuels, oils and many solvents. Mineral acids, even dilute, and strong oxidisers attack it, and it absorbs water.

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.

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.
