Material comparison at 20 °C
Resistance overview
ECTFE/ETFE shows very good resistance (A) to Cresol 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
Cresol is commonly encountered in cosmetics production and chemical synthesis. ECTFE/ETFE (Ethylene chlorotrifluoroethylene / ethylene tetrafluoroethylene) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. Because Cresol is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.
Practical recommendation
ECTFE/ETFE can be used with confidence for Cresol 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 Cresol in contact with the base fluoropolymer. In real-world applications, additives, pigments, and fillers in the material can shift resistance in either direction.

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.
