Resistance overview
PVC Rigid shows excellent resistance to Sodium Peroxide across all 2 tested concentrations (10 %, saturated) at 20 °C, making it a reliable choice for storage, transfer, and handling applications involving this chemical at any of the tested strengths. 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 bleaching and waste treatment. PVC Rigid (Rigid (unplasticised) polyvinyl chloride) 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
PVC Rigid can be used with confidence for Sodium Peroxide containment and handling. The A rating indicates that the material shows no significant change in weight, dimensions, or mechanical properties after prolonged contact under test conditions. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.
Did you know?
Temperature is often the deciding factor when selecting materials for Sodium Peroxide: even materials rated A at 20 °C may lose performance at elevated temperatures.

About PVC Rigid
Rigid PVC resists acids, alkalis and salt solutions well. Ketones, esters, aromatic and chlorinated solvents dissolve or swell it. Service temperature is limited to about 60 °C.

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.
