Resistance overview
PVC Flexible shows excellent resistance to Sodium Hypochlorite (Bleach) across all 2 tested concentrations (12,5 % Cl, dilute) 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 Hypochlorite (Bleach) is commonly encountered in water disinfection and pulp and paper. PVC Flexible (Flexible (plasticised) polyvinyl chloride) is a thermoplastic typically used for tanks, piping, containers and liners. Because Sodium Hypochlorite (Bleach) is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
No resistance data is available for PVC Flexible in contact with Sodium Hypochlorite (Bleach). Before using this combination, consult the material manufacturer or conduct independent testing.
Did you know?
Temperature is often the deciding factor when selecting materials for Sodium Hypochlorite (Bleach): even materials rated A at 20 °C may lose performance at elevated temperatures.

About PVC Flexible
Flexible PVC shares the solvent weaknesses of rigid PVC, and any liquid that extracts the plasticiser also hardens it. It is generally less resistant than rigid PVC.
Rating scale
- A very good resistance
- B good resistance
- C limited resistance
- D not resistant

- K no general statement possible
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.
