Resistance overview
HDPE shows excellent resistance to Hydrogen Peroxide across all 4 tested concentrations (3 %, 30 %, 90 %, 100 %) at 20 °C, making it a reliable choice for storage, transfer, and handling applications involving this chemical at any of the tested strengths. However, at 50 °C the resistance rating drops, indicating that temperature must be factored into the design. For heated applications, additional testing under actual service conditions is strongly recommended.
Application context
Hydrogen Peroxide is commonly encountered in bleaching and chemical processing. HDPE (High-density polyethylene) is a thermoplastic typically used for tanks, piping, containers and liners. Because Hydrogen Peroxide is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
HDPE can be used with confidence for Hydrogen 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. At elevated temperatures (50 °C), some reduction in resistance occurs, so periodic inspection is advisable for heated applications. Always verify performance under actual operating conditions before committing to a design.
Did you know?
Temperature is often the deciding factor when selecting materials for Hydrogen Peroxide: even materials rated A at 20 °C may lose performance at elevated temperatures.

About HDPE
High-density polyethylene resists most aqueous acids, alkalis and salt solutions. Strong oxidising acids, chlorinated solvents and aromatic hydrocarbons attack or swell it. Continuous service is usually limited to about 80 °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.
