Resistance overview
The resistance of PVC Rigid to Succinic Acid is concentration-dependent. Across the 2 tested concentrations (50 %, saturated), the 20 °C rating ranges from A at lower concentrations to C at higher ones. This means engineers must verify which concentration their process actually involves before relying on a single rating. 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
Succinic Acid is commonly encountered in water treatment and surface cleaning. PVC Rigid (Rigid (unplasticised) polyvinyl chloride) is a thermoplastic typically used for tanks, piping, containers and liners. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
PVC Rigid is suitable for use with Succinic Acid under normal conditions, but some minor effects on the material are expected over time. Periodic monitoring for swelling, softening, or weight change is recommended, especially for long-service components. Avoid prolonged exposure at elevated temperatures, as the resistance decreases further at 50 °C. For safety-critical or long-life applications, consider HDPE, LDPE, PP instead, which are rated A for this chemical.
Did you know?
Rigid (unplasticised) polyvinyl chloride is commonly chosen for tanks, piping, containers and liners because of its combination of chemical resistance, mechanical strength, and cost-effectiveness.

About PVC Rigid
Rigid PVC resists acids, alkalis and salt solutions well. Ketones, esters, aromatic and chlorinated solvents dissolve or swell it. Service temperature is limited to about 60 °C.
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.
