Is EPDM chemical resistant?

While EPDM is compatible with a wide range of chemicals, it offers no resistance to hydrocarbon fluids. Additionally, EPDM seals absorb oil and gas, making them a weak defense in oil and gas applications.

Is EPDM chemical resistance?

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.

Does chlorine damage EPDM?

Chlorine causes depolymerisation, an oxidation that takes place on the liner surface and makes the sheet surface of Butyl become soft and tacky. With EPDM the surface becomes much harder and more brittle. Chlorine concentrations constantly higher than 0.2mg/l will also have an effect on the lifetime of liners.

Is EPDM compatible with hydraulic oil?

Ethylenepropylene-diene rubber (EPDM) is produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base.

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.

Chemical Resistant EPDM O-rings

Is EPDM good for alcohol?

EPDM has very good compatibility with drinking water, anti-freeze, glycol hydraulic fluids, alcohol, hot water, steam, cleaning agents, organic and inorganic acids, dilute acids and alkalis, ketones, phosphate ester hydraulic fluids and automotive brake fluids.

Does hydrochloric acid react with rubber?

The acid reacts with natural rubber hydrocarbon to chlorinate the surface, making an impermeable membrane. In concentrated hydrochloric acid, it only takes approximately three months for natural rubber crust formations to be in the range of 1/64 (. 016″) thickness in depth.

Is EPDM good for caustic?

EPDM has good resistance to many chemical products like detergents, caustic potash solutions, sodium hydroxide solutions, and many other diluted acids and chemicals. It is not resistant to most hydrocarbons, such as oils, kerosene, gasoline, and many solvents.

Is EPDM chloramine resistant?

Traditional EPDM materials, unless specifically formulated to resist chloramines, exhibit severe volume swell and physical deterioration when exposed to high concentrations (50 ppm) or long exposure times in water. Parker E1257-70 EPDM has been developed specifically for chloramine resistance.

What does oil do to EPDM?

EPDM has an excellent mechanical properties and very wide temperature range: from -50°C up to +150°C (hot steam up to +180°C). Due to very saturated structure EPDM has a very good ozone, weather and ageing resistance. Mineral oils and lubricants, as well as organic oils and adipose, causes severe swelling.

Is EPDM good for saltwater?

The strength of EPDM lies in its good temperature, weather and seawater resistance as well as in its resistance to polar chemicals.

Is EPDM impact resistant?

The impact resistance of both the field-aged and heat-aged membrane also clearly demon- strates that EPDM retains the bulk of its impact resistance as it ages.

What is the difference between Viton and EPDM?

Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.

What is the difference between NBR and EPDM?

What is the Difference Between NBR and EPDM? NBR and EPDM are two types of rubber materials. NBR stands for Nitrile Butadiene Rubber while EPDM stands for Ethylene Propylene Diene Monomer Rubber. The key difference between NBR and EPDM is that NBR is a non-aromatic polymer compound, whereas EPDM is an aromatic polymer.

What dissolves EPDM rubber?

EPDM rubber is soluble in petroleum ether, n-hexane, cyclohexane.

What chemical will dissolve rubber?

Carbon disulphide is used to dissolve rubber but it will not be easy to buy nor will it be easy to work with unless you have a laboratory.

What acid eats through rubber?

Acetic acid is an organic acid that is especially harmful to Viton ad Buna-N rubber seals. Organic acids are made up of carbon, and mineral acids are made up of mineral elements. Hydrochloric, hydrofluoric, and sulfuric acid also attack and negatively impact Buna-N rubber.

Is EPDM good for diesel?

In addition to gasoline, diesel fuel, and motor oil, EPDM is not recommended for use with synthetic diester oils, lubricants found in some types of industrial machinery. EPDM also provides unsatisfactory resistance to Freon, a category of fluorocarbons that are used as refrigerants.

Which is better EPDM or neoprene?

Neoprene has superior attributes in comparison to EPDM in applications requiring good resistance to Oils, Chemicals, Hydrocarbons and Solvents. EPDM, on the other hand, has superior attributes in comparison to Neoprene in applications requiring good resistance to UV Light, Ozone and external weathering.

Is EPDM suitable for natural gas?

However, EPDM rubber is not suitable for use with hydrocarbon (petroleum) oils and greases, natural gas, mineral oils.

What rubber is resistant to gasoline?

The best fuel resistant gasket material for gasoline is Nitrile (Buna-N), a closed-cell sponge rubber material that provides excellent gasket material for sealing applications that require resistance to gasoline, oil, fuels, as well as solvents, hydraulic fluids, and mineral and vegetable oils.

Is PVC resistant to sulfuric acid?

PVC is resistant to many alcohols, fats, oils and aromatic free petrol. It is also resistant to most common corroding agents including inorganic acids, alkalis and salts.

Is rubber corrosion resistant?

Rubber is electrochemically inert, and has corrosion resistant properties in a wide range of inorganic and organic compounds. There are also synthetic rubbers which can resist chemicals with strong oxidizing properties and organic solvents.
