What is EPDM? General Properties, Compatibility & More

EPDM (ethylene-propylene diene monomer [M-class] rubber) is a type of synthetic rubber that is popular for a broad spectrum of applications. It is one of the most versatile and durable rubbers available, providing outstanding heat, weather, and ozone resistance.

EPDM rubber is suitable for used in extreme cold temperatures (as low as -60°F/-51°C) and outdoor applications, and is resistant to steam (up to 300°F/150°C), hot water, direct sunlight/UV, silicone oils and greases, dilute acids, ketones, alkalis, and automotive break fluids. It also makes an excellent electrical insulator.

Versatile O-Ring, Seal & Gasket Material

EPDM o-rings, gaskets, and seals are commonly used in automotive manufacturing, medical devices, household appliances, water and wastewater systems, and other challenging applications.

In other forms, EPDM rubber is used for everything from garden hose to roofing membranes to speaker components.

EPDM Gaskets Manufactured by Ace Seal

EPDM gaskets provide a variety of benefits compared to other rubber gasket materials. Capable of withstanding harsh environmental conditions, EPDM gaskets provide long-lasting sealing power in temperatures ranging from -60° to 300°F. These gaskets also offer excellent electrical insulation and are highly resistant to UV light, wind, harsh weather conditions, and ozone. As such, EPDM gaskets are a cost-effective and high-performing option for a number of outdoor and electrical applications.

As a leading manufacturer of gaskets for any industry, Ace Seal can provide you with the high-quality EPDM gaskets required for your application. Contact us today to begin discussing your project needs. 

Compare & Contrast: EPDM vs. Silicone

EPDM and silicone are very similar materials, and share a number of like characteristics. Both are good for outdoor applications, with good resistance to weathering, UV exposure, and aging. EPDM and silicone both provide excellent ozone resistance and maintain their flexibility in extremely low temperatures.

However, EPDM provides far superior abrasion, tear, and cut growth resistance, as well as higher tensile strength. Contact Ace Seal to discuss your application and our experts will help you determine which material is best suited to your unique needs.
