Material comparison at 20 °C
Resistance overview
ECTFE/ETFE 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 power generation and automotive. ECTFE/ETFE (Ethylene chlorotrifluoroethylene / ethylene tetrafluoroethylene) 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
ECTFE/ETFE 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?
Ethylene chlorotrifluoroethylene / ethylene tetrafluoroethylene is commonly chosen for seals, gaskets, valve seats and lined equipment because of its combination of chemical resistance, mechanical strength, and cost-effectiveness.

About ECTFE/ETFE
ECTFE and ETFE are tough fluoropolymers with broad resistance. Hot amines and some chlorinated solvents at elevated temperature are their main limits.

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.
