Material comparison at 20 °C
Resistance overview
EPDM has limited resistance (C) to Ethyl Acetate at 100 % at 20 °C. This indicates that the chemical has a noticeable effect on the material, which may include visible swelling, softening, or a measurable loss of tensile strength. Use is generally limited to short-term or intermittent contact where full structural integrity is not required. 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
Ethyl Acetate is commonly encountered in cleaning and degreasing and pharmaceutical manufacturing. EPDM (Ethylene propylene diene rubber) is an elastomer typically used for seals, O-rings, hoses and flexible connections. Since Ethyl Acetate 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
EPDM has limited resistance to Ethyl Acetate and should only be used for short-term or intermittent contact at ambient temperature. The C rating means the material undergoes noticeable changes — swelling, loss of strength, or surface degradation — that make it unsuitable for permanent installations. For prolonged or continuous exposure, HDPE, Nylon (PA), Acetal (POM) offer significantly better resistance and are rated A.
Did you know?
Ethylene propylene diene rubber is commonly chosen for seals, O-rings, hoses and flexible connections because of its combination of chemical resistance, mechanical strength, and cost-effectiveness.

About EPDM
EPDM resists water, steam, alkalis, ketones and alcohols. Mineral oils, fuels and aromatic solvents swell it severely.

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.
