Resistance overview
Viton (FPM) is not resistant (D) to Calcium Acetate at aqueous and should not be used in direct contact. The chemical is expected to cause rapid degradation, which can include dissolution, cracking, severe swelling, or complete structural failure of the material.
Application context
Calcium Acetate is commonly encountered in chemical storage and de-icing. Viton (FPM) (Fluoroelastomer (FKM/FPM)) is an elastomer typically used for seals, O-rings, hoses and flexible connections. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
Viton (FPM) is not recommended for use with Calcium Acetate. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using HDPE, LDPE, Polycarbonate instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
Fluoroelastomer (FKM/FPM) was first developed in the 1950s and remains one of the most widely used elastomers in chemical handling equipment.

About Viton (FPM)
Fluoroelastomer (Viton, FKM/FPM) resists fuels, oils and many acids. Ketones, esters, amines and hot water or steam attack it.
Rating scale
- A very good resistance
- B good resistance
- C limited resistance
- D not resistant
- – no data
- K no general statement possible
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.
