EPDM seals and Gaskets are used widely with vehicles and equipment, but this synthetic elastomer has unsatisfactory resistance to gasoline, diesel fuel and motor oil. EPDM`s advantages are numerous, however, and this cost-effective compound is often a better choice than silicones – especially in outdoor environments.

Ethylene Popylene diene monomer (EPDM) is a compound that resists sunlight, ozone, oxygen, acids, water and severe weather conditions. This odor-free elastomer also provides excellent color stability and high heat resistance. Depending on the compound`s chemistry, servile temperatures can range from -70 degrees to 250 degrees. All EPDM rubber isn`t the same, so differences in ethylene content and the dienes that are used can affect physical properties.

The following are the physical properties of rubber:

– Specific Gravity
– Abrassion Resistance
– Tear Resistance
– Compression Set
– Resilience
– Elongation
– Tensile Modulus
– Tensile Strength
– Hardness

EPDM is often used instead of silicones, nitrile or Thermoplastic Elastomers (TPEs)
