EPDM rubber (ethylene propylene diene monomer rubber), a type of synthetic rubber, is an elastomer characterized by a wide range of applications. EPDM is compatible with polar substances, e.g. fireproof hydraulic fluids, ketones, hot and cold water, and alkalis. It is incompatible with most hydrocarbons, such as oils, kerosene, aromatic, gasoline, as well halogenated solvents. EPDM exhibits outstanding resistance to heat, ozone, steam and weather. It is an electrical insulator.
Advantages to using EPDM
EPDM has excellent water resistance, both fresh and salt, as well as being very good with ozone, UV and oxidation. The temperature and weathering properties of EPDM rubber are also outstanding. These factors make EPDM ideal for use in water and it is often the material of choice for potable water applications.
