Material comparison at 20 °C
Resistance overview
PVC Flexible shows very good resistance (A) to Silver Nitrate 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
Silver Nitrate is commonly encountered in water treatment and de-icing. PVC Flexible (Flexible (plasticised) polyvinyl chloride) is a thermoplastic typically used for tanks, piping, containers and liners. Because Silver Nitrate is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
PVC Flexible can be used with confidence for Silver Nitrate 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?
The ratings shown here apply to pure Silver Nitrate 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

- B good resistance
- C limited resistance

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.
