EPDM is a versatile synthetic rubber that manufacturers use to produce highly durable components for use in commercial and industrial applications. Its desirable properties make it a popular option across various industries, ranging from construction and appliances to aerospace, automotive, and more.
Ethylene propylene diene monomer (EPDM) rubber is a popular M-Class rubber under standard D-1418 established by ASTM. The propylene base has been polymerized to reduce its structure to semi-crystalline, giving it enhanced elasticity and flexibility. Because of its synthetic polymer composition, EPDM rubber is more durable than natural rubbers, neoprene, and SBR options for applications that involve exposure to heat, sunlight, or ozone. Manufacturers can also enhance EPDM rubber’s resistance to temperature damage, further extending its lifespan in critical exterior applications.
EPDM is electrically insulative and compatible with alkalis, water, and ketones. However, it is incompatible with oils, halogenated solvents, and many other chemicals.
What Is EPDM Rubber Used For?
Because of its strong positive characteristics, EPDM rubber is a popular choice for fabricating a wide range of components. Its elasticity and soft, flexible structure make it an excellent choice for components that need to bend to create a leak-proof seal. Some of the most common uses for EPDM rubber include:
- Seals
- Gaskets
- Diaphragm components
- Membranes
- Weatherstripping
- Hoses
- O-rings
- Slip-resistant coatings on walking surfaces, playgrounds, and more
Many of these components and use cases can be found across every industry, making EPDM rubber the go-to material for any manufacturing project that needs to produce durable, flexible, and reliable components.
Industries That Use EPDM Rubber
At Thomas A. Caserta, we’ve been producing high-performance rubber parts and components for over 70 years. We’re a leading provider of precision engineering services, and we’re committed to providing quality at an affordable price. We serve clients across diverse markets with EPDM washers, gaskets, bushings, tubing, and more. Some of the industries we serve include:
Construction
Our EPDM rubber components can be used in heavy-duty highway equipment and drilling equipment.
Aerospace
We can produce custom EPDM components for lightweight assemblies and leak-proof seals in avionic and aeronautic vehicles.
Appliances
We produce EPDM gaskets, seals, and more for use in consumer appliances and equipment.
Automotive
Some of the most common applications for EPDM rubber components in automotive manufacturing include shock absorber mountings that absorb the force from movement and rattling to protect components in the assembly. Our EPDM rubber components also include gear shift components, rubber parts in suspension systems, and specialty components for internal combustion engines.
Sealing Applications
EPDM rubber is particularly well-suited for sealing applications because it can easily be used to fabricate components with custom profiles and dimensions. The rubber is also resistant to water and can flex to create a reliable, long-term seal, even in exterior applications and extreme environments. EPDM rubber seals can be used alongside pipes, tubes, and wires.
The following industries also rely on EPDM rubber components:
- Electrical
- Fastening
- OEMs
- Plumbing
- Skateboards and bikes
How Strong Is EPDM Rubber?
EPDM rubber is strong enough to resist damage from sunlight, ozone, and other environmental factors. It also has excellent heat resistance and tear resistance.
How Long Does EPDM Rubber Last?
EPDM rubber roof membranes have a long lifespan of over 50 years because of their chemical stability and resistance to damage from the elements. EPDM rubber can also be used to produce long-lasting seals and gaskets that last for years. The durability, stability, and flexibility of EPDM ensure a long service life; however, exposure to certain oils and solvents can cause degradation.
