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.
