Material comparison at 20 °C
Resistance overview
PVDF shows very good resistance (A) to Gasoline (Petrol) at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.
Application context
Gasoline (Petrol) is commonly encountered in fuel storage and transfer and power generation. PVDF (Polyvinylidene fluoride) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. 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
PVDF can be used with confidence for Gasoline (Petrol) 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. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.
Did you know?
When choosing between fluoropolymers for Gasoline (Petrol) service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

About PVDF
PVDF resists acids, halogens and hydrocarbons. Strong bases, amines, ketones and esters attack it. Service temperature is up to about 150 °C.

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.
