Material comparison at 20 °C
Resistance overview
ECTFE/ETFE shows very good resistance (A) to Mercury(II) Chloride at aqueous 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
Mercury(II) Chloride is commonly encountered in bleaching and chemical processing. ECTFE/ETFE (Ethylene chlorotrifluoroethylene / ethylene tetrafluoroethylene) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. Because Mercury(II) Chloride 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 Mercury(II) Chloride 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 ratings shown here apply to pure Mercury(II) Chloride 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.
