Resistance overview
Viton (FPM) is not resistant (D) to Methyl Acrylate 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
Methyl Acrylate is commonly encountered in chemical synthesis and coatings and paints. Viton (FPM) (Fluoroelastomer (FKM/FPM)) is an elastomer typically used for seals, O-rings, hoses and flexible connections. Since Methyl Acrylate 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
Viton (FPM) is not recommended for use with Methyl Acrylate. 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 FEP, PTFE, Aluminium instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
The ratings shown here apply to pure Methyl Acrylate in contact with the base elastomer. In real-world applications, additives, pigments, and fillers in the material can shift resistance in either direction.

About Viton (FPM)
Fluoroelastomer (Viton, FKM/FPM) resists fuels, oils and many acids. Ketones, esters, amines and hot water or steam attack it.

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.
