There are two basic types of rubber available for use in rubber extrusions. There is EP rubber or EPDM rubber. EPDM is one of the most widely utilized synthetic rubbers on the market.
EPDM is a terpolymer that combines ethylene, propylene, and a diene monomer and uses a sulfur cure system.
As a rubber it has excellent resistance to weather aging, ozone, UV exposure, water, heat, diluted acids, and electrical insulation. It’s even resistant to steam, oxygenated solvents, animal and vegetable oils, and other chemicals.
Unfortunately, EPDM is not recommended for use with petroleum oils, fluids, or solvents. Each of these items can cause significant swelling in the products using EPDM. It also exhibits poor resistance to hydrocarbons such as Benzol, kerosene, and turpentine.
This synthetic rubber is widely used in several applications. EPDM is most commonly used in outdoor applications or products that require resistance to weather and water. For instance, EPDM is used throughout the automotive industry and with HVAC. EPDM is also used on conveyor belts.
EPDM is just one of several materials used at ELBEX to manufacture rubber extrusions and other products seen in a broad range of applications. Contact our team today to see if EPDM is right for your project requirements.
