Resistance overview
ECTFE/ETFE shows excellent resistance to Resorcinol across all 2 tested concentrations (5 %, saturated) at 20 °C, making it a reliable choice for storage, transfer, and handling applications involving this chemical at any of the tested strengths. 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
Resorcinol is commonly encountered in food processing and electroplating. ECTFE/ETFE (Ethylene chlorotrifluoroethylene / ethylene tetrafluoroethylene) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
ECTFE/ETFE can be used with confidence for Resorcinol 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?
When choosing between fluoropolymers for Resorcinol service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

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.
