Material comparison at 20 °C
Resistance overview
PVC Rigid shows good but limited resistance (B) to Gasoline (Petrol) at 20 °C. The material can be used in contact with this chemical, but minor effects such as slight swelling or a small reduction in mechanical properties may occur over extended exposure periods. Regular inspection of components in service is advisable. 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
Gasoline (Petrol) is commonly encountered in marine applications and automotive. PVC Rigid (Rigid (unplasticised) polyvinyl chloride) is a thermoplastic typically used for tanks, piping, containers and liners. Since Gasoline (Petrol) is flammable, material selection must also consider the risk of static charge buildup and the need for proper grounding in storage and transfer systems.
Practical recommendation
PVC Rigid is suitable for use with Gasoline (Petrol) 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 Nylon (PA), Acetal (POM), ECTFE/ETFE instead, which are rated A for this chemical.
Did you know?
The ratings shown here apply to pure Gasoline (Petrol) 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 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
- – no data
- 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.
