2011-6-16 12:22:48
| Material | General Properties | Resistant to: | Attacked by: |
| SBR | Good physical properties and abrasion resistance. Poor resistance to petroleum-based fluids. Common applications include water pipeline flange gaskets, plumbing washers. | Most moderate chemicals, wet or dry, organic acids, alcohols, ketones, aldehydes. | Ozone, strong acids, fats, oils, greases, most hydrocarbons. |
| Neoprene | Low cost option suitable for most rubber washer needs. Neoprene offers good weather resistance, flame retardance, and moderate resistance to petroleum-based fluids. Commonly used for water and air line seals, many other applications. | Moderate chemicals and acids, ozone, oils, fats, greases, many oils, and solvents. | Strong oxidizing acids, esters, ketones, chlorinated, aromatic and nitro hydrocarbons. |
| EPDM | Excellent ozone, chemical, and aging resistance but poor resistance to petroleum-based fluids. Economical choice where weather and chemical resistance are important features. | Animal and vegetable oils, ozone, strong and oxidizing chemicals. | Mineral oils and solvents, aromatic hydrocarbons. |
| NBR | Excellent resistance to petroleum-based fluids. Good physical properties. Economical choice for gaskets and seals in gas engines and other equipment where petroleum-based oils, lubricants, and fuels are present. | Many hydrocarbons, fats, oils, greases, hydraulic fluids, chemicals. | Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated and nitro hydrocarbons. |
| Silicone | Excellent high and low temperature properties. Fair physical properties. | Moderate or oxidizing chemicals, ozone, concentrated sodium hydroxide. | Many solvents, oils, concentrated acids, dilute sodium hydroxide. |
| Viton (Fluoro-elastomer) | Excellent oil and air resistance both at low and high temperatures. Very good chemical resistance. | All aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. | Ketones, low molecular weight esters and nitro containing compounds. |
