EPDM rubber or Ethylene propylene diene monomer rubber is used for many purposes. Considered to be the most water resistant rubber among all types of rubber, EPDM rubber is widely used for manufacturing of sheeting used at high temperatures. In fact, EPDM rubber is one of the most commonly used and fastest growing synthetic rubbers having both general-purpose and specialty applications.

EPDM elastomers have a fair tensile strength and excellent resistance to weathering, ozone and chemicals. They also exhibit excellent electrical insulation properties. Due to its weather, heat and ozone resistance, EPDM is the perfect hose cover, especially for outdoor environments. High-temperature tolerance— between 150°C (302°F) and 204°C (400°F) in water or steam)—makes EPDM an excellent steam hose, and it is also a great choice for conveying low and high pH fluid.

Properties of EPDM Rubber

There are many properties of ethylene propylene diene monomer rubber or the EPDM rubber which makes it one of the most popular synthetic rubber.

• EPDM rubber has excellent resistance to atmospheric aging meaning it is heat, ozone and weather resistant
• It has a good resistance to most water-based chemicals.
• EPDM rubber also has a great resistance to abrasives and tearing.
• It has stable, saturated polymer backbone structure.
• It has good electrical resistivity.
• EPDM rubber is also resistant to polar solvents like water, acids, alkalies, phosphate esters.
• It has excellent flexibility at high and low temperatures.
• EPDM rubber can be finished to an extremely smooth surface
• It has resistance to solvents and high temperatures too.

However, EPDM is not oil resistant—thus unsuitable for fuel transfer hose—and can also be very costly.
