Material Properties of EPDM, NBR, and FPM Rubber Seals ...

If you're dealing with rubber seals, it's crucial to understand the material properties of EPDM, NBR, and FPM. Each type offers distinct benefits, making them suitable for various applications. Let’s delve deeper into these properties and how they compare.

EPDM (Ethylene Propylene Diene Monomer) Rubber

EPDM rubber is known for its excellent resistance to heat, ozone, and weather conditions, making it ideal for outdoor applications. This material also has good insulation properties and can withstand temperatures ranging from -50°C to 120°C. EPDM is commonly used in automotive weatherstripping, roofing membranes, and appliances.

NBR (Nitrile Butadiene Rubber) Rubber

NBR rubber is renowned for its excellent oil and fuel resistance, making it the preferred choice for seals and gaskets in automotive and industrial applications. NBR can operate at temperatures ranging from -40°C to 120°C. It also offers good abrasion resistance, making it suitable for heavy-duty applications.

FPM (Fluoroelastomer) Rubber

FPM rubber, also known as FKM, is known for its outstanding high-temperature resistance and chemical inertness. Commonly used in applications requiring exposure to aggressive chemicals and fuels, FPM rubber can withstand temperatures up to 200°C. This makes it ideal for aerospace and chemical processing industries.

NBR Rubber vs. FKM Rubber

Both NBR and FKM (FPM) rubber are thermoset elastomers with specific properties suitable for different conditions. While both materials perform well under various conditions, each has its unique strengths and limitations. For each property compared, the top bar represents NBR rubber, while the bottom bar represents FKM rubber.

Oil and Fuel Resistance

NBR rubber offers excellent resistance to oil and fuel, making it ideal for automotive applications. FKM also provides outstanding fuel resistance but is better suited for applications requiring high-temperature tolerance and chemical resistance.

Temperature Range

NBR rubber can operate within a temperature range of -40°C to 120°C, making it suitable for various industrial applications. On the other hand, FKM rubber can endure extreme temperatures up to 200°C, making it more suitable for high-temperature and aggressive chemical environments.
