Is EPDM rubber chemical resistant?
EPDM has poor resistance to oil, gasoline and hydrocarbon solvents. The physical properties of NBR meet the requirements of EN 681:1. NBR is used in specific applications for ef- fluent contaminated with hydrocarbons, oils, fats and greases.
Is EPDM compatible with HCl?
A = Excellent. B = Good. Minor Effect. Slight corrosion or discoloration….Guide to Impact of Chemicals on EPDM Rubber.
| Chemical | Compatibility |
|---|---|
| Aqua Regia (80% HCl, 20% HNO3) | C-Fair |
| Arochlor 1248 | B-Good |
| Aromatic Hydrocarbons | D-Severe Effect |
| Arsenic Acid | A-Excellent |
Is EPDM resistant to diesel?
EPDM has poor resistance to oil, gasoline and hydrocarbon solvents. The physical properties of NBR meet the requirements of EN 681:1.
Is EPDM good for sulfuric acid?
EPDM has good abrasion and tear resistance to a variety of acids and bases. It is susceptible to attack by oils and is not recommended for applications involving petroleum oils, strong acids or strong bases. It has exceptionally good weather aging and ozone resistance.
Is EPDM resistant to acetone?
Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment….LEGEND: 1 = Satisfactory, 2 = Fair, 3 = Doubtful, 4 = Unsatisfactory, X = Insufficient Data.

| Nitrile | 3 |
| EPDM | 1 |
| Neoprene | 1 |
| SBR | 1 |
Is EPDM gasoline resistant?
Ethylene-propylene diene monomer (EPDM) is valuable synthetic rubber for its excellent thermal aging and ozone resistance due to a highly unsaturated backbone. Nevertheless, it exhibits unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons due to nonpolarity.
Is EPDM hose fuel resistant?
Ethylene Propylene Diene Monomer (EPDM) is the product of Ethylene and Polypropylene polymerization. EPDM elastomers have a fair tensile strength and excellent resistance to weathering, ozone and chemicals. However, EPDM is not oil resistant—thus unsuitable for fuel transfer hose—and can also be very costly.
How do you dissolve EPDM rubber?

Is EPDM good for oil?
Mechanical Properties (hardness, tensile strength, extensibility, flex cracking resistance, tear resistance & abrasion resistance) Operating Temperature Range. Resistance To Heat, UV, Oxygen, Ozone & Miscellaneous Chemicals….Which Elastomer Offers The Best Oil & Fuel Resistance?
| Elastomer | Oil Resistance | Fuel Resistance |
|---|---|---|
| EPDM | Poor | Poor |
| Natural Rubber | Poor | Poor |
| SBR | Poor | Poor |
At what temperature does EPDM melt?
Ethylene-Propylene-Diene-Rubber-Mixture (EPDM) The glass transition was detected at –52.5°C. The melting above the glass transition (peak temperature at 31.4°C) is typical for the behavior of a sequence-type EPDM. The further endothermal effects (at 98.6°C and 110°C) are due to the evaporation of processing agents.
What kind of chemical resistance does EPDM gasket have?
EPDM Gasket Chemical Resistance. EPDM has good resistance to nitrogen, potassium and sodium. Due to its low taint and taste, and excellent UV resistance, it is often used in water-based external environments. Any water pipe applications that has high volumes of sodium, or nitrogen, are commonly sealed using EPDM.
Which is gasket material has the best chemical resistance?
Chemical Compatibility & Resistance Nitrile (NBR) Gasket Chemical Resistance. Nitrile (or NBR) rubber is used with fuels and oils. It has very good… EPDM Gasket Chemical Resistance. EPDM has good resistance to nitrogen, potassium and sodium. Due to its low taint and… Viton Gasket Chemical
What should I consider when designing a gasket?
When designing a gasket or seal, chemical resistance is one of the most important steps to consider. For more information on compatibility with specific chemicals please see our chemical compatibility charts. Nitrile (or NBR) rubber is used with fuels and oils.
Why do you need a chemical resistance chart for rubber?
Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment. The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with.
