Degradation of Rubber
The composition of the atmosphere plays an equally important role. For example, ozone, even when present in very small concentration, will cause extensive cracking perpendicular to the stress in the rubber. References. Y.S. Duh, T.C. Ho, J.R. Chen, and C.S. Kao, Polymers 2, 174-187 (2010)
What is EPDM Rubber?
Most elastomers cannot hold a candle to natural rubber in such categories. While EPDM does have decent physical properties, they are not on the same level as natural rubber. However, EPDM rubber can brag about its resistances to UV and ozone, a quality that is natural rubber’s most glaring weakness.

EPDM Rubber. EPDM also has its strengths and weaknesses. A popular polymer, this synthetic rubber is used in belts, hoses, and O-rings for the automotive and mass transit industries. With its excellent resistance to aging, ozone, and weathering, EPDM also provides strong resistance to acids, alkalis, and some solvents.
General Properties of Elastomers
Natural rubber deteriorates when exposed to oils, fuels, solvents, petroleum derivatives, and hydraulic fluids. Without special additives, natural rubber has poor resistance to sunlight, oxygen, ozone, and high temperatures. COMMON APPLICATIONS: Natural rubber can be easily bonded to a wide variety of materials, including fabric and metal.
EPDM Rubber - ACME Rubber
EPDM RUBBER can be Sulphur or Peroxide cured. Most common cure for EPDM RUBBER is Sulfur due to cost. EPDM can be made in durometer hardness of 40 to 90 Shore A.Sulfur cured EPDM RUBBER has a operating temperature of -50 to 220°F and Peroxide cured EPDM has a operating temperature of -50 to 280°F.
