Resistance overview
PVC Flexible is not resistant (D) to Ethylenediamine at technical grade and should not be used in direct contact. The chemical is expected to cause rapid degradation, which can include dissolution, cracking, severe swelling, or complete structural failure of the material.
Application context
Ethylenediamine is commonly encountered in chemical processing and water treatment. PVC Flexible (Flexible (plasticised) polyvinyl chloride) is a thermoplastic typically used for tanks, piping, containers and liners. Because Ethylenediamine is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
PVC Flexible is not recommended for use with Ethylenediamine. 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 HDPE, LDPE, Nylon (PA) instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
Flexible (plasticised) polyvinyl chloride was first developed in the 1920s and remains one of the most widely used thermoplastics in chemical handling equipment.

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.

- 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.
