Material comparison at 20 °C
Resistance overview
PVC Flexible shows very good resistance (A) to Ammonium Hydroxide (Ammonia Solution) at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. 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
Ammonium Hydroxide (Ammonia Solution) is commonly encountered in water treatment and cleaning and sanitation. PVC Flexible (Flexible (plasticised) polyvinyl chloride) is a thermoplastic typically used for tanks, piping, containers and liners. Because Ammonium Hydroxide (Ammonia Solution) 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 Ammonium Hydroxide (Ammonia Solution). Before using this combination, consult the material manufacturer or conduct independent testing.
Did you know?
The ratings shown here apply to pure Ammonium Hydroxide (Ammonia Solution) in contact with the base thermoplastic. In real-world applications, additives, pigments, and fillers in the material can shift resistance in either direction.

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 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.
