Material comparison at 20 °C
Resistance overview
ECTFE/ETFE shows very good resistance (A) to Amyl Alcohol (1-Pentanol) 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
Amyl Alcohol (1-Pentanol) is commonly encountered in food and beverage processing and cosmetics production. ECTFE/ETFE (Ethylene chlorotrifluoroethylene / ethylene tetrafluoroethylene) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. Since Amyl Alcohol (1-Pentanol) 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 Amyl Alcohol (1-Pentanol) 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?
The chemical resistance of ECTFE/ETFE depends not only on the chemical concentration but also on exposure time, mechanical stress, and the presence of other chemicals in the mixture.

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.
