EPDM seals (ethylene propylene diene monomer) are manufactured using a complex elastomer that has a wide range of uses and is great for sealing solutions in many applications. Its properties are particularly resilient to heat and certain chemicals, meaning the elastomer is used across a wide range of industries.
EPDM operating temperatures range from -60 to 288°C, meaning it is excellent for applications with harsh temperatures and it is typically used for protection against weathering issues in a variety of applications.
EPDM seals have excellent heat and steam resistance, whilst many other elastomer polymers have temperature resistance, only few can deal with both high and low temperatures the way EPDM does, making it the first choice in applications within a colder environment.
The compounds found within EPDM elastomers will withstand the effect of greases, sodium hydroxide solutions and many other diluted acids. However, it is important to note that EPDM seals do not perform well against chemical media with mineral oil products, lubricants, oils and fuels.
EPDM is suitable for most sealing requirements, but it is always better to seek expert advice when choosing the right elastomer material for your application.
EPDM seals, o-rings and gaskets are commonly used in medical devices, automotive, household appliances, water systems, and other challenging environments.
With its strong combination of thermal and mechanical properties, you can expect to see EPDM elastomer in your everyday life including, door and window seals, refrigerators and in your cars.
The attributes of EPDM seals make it ideal for use in the automotive industry and provides a strong barrier against weather factors and attenuate vibration from the engine compartment.
Whilst EPDM seals are widely used in various industries due to its value and versatility, it does have some limitations. The stand-out disadvantage is its resistance to certain categories of chemicals as mentioned above. EPDM elastomers are not recommended for use with synthetic diester oils and lubricants found in some types of industrial machinery.
