In the parts manufacturing world, it can be hard to determine what works best for your parts.
Today, we’re focusing on EPDM rubber for fabricated parts and discussing what you need to know when reviewing this material.
This article will cover EPDM rubber: its advantages and disadvantages and recommended applications. This will help you determine whether EPDM rubber is the right material for your product needs.
What is EPDM (Ethylene Propylene Diene Monomer) Rubber?
Ethylene propylene diene monomer, more commonly known as EPDM rubber, is a synthetic rubber with a single bond molecular structure and chemically saturated base. In simple terms, it’s a durable rubber that holds up well in the outdoors due to its weather resistance. The material is impenetrable by ozone and UV rays and is the most waterproof rubber you can find in the industrial field.
Advantages of EPDM
The biggest advantage of EPDM rubber is its extremely waterproof and weatherproof properties. This ultra-strong rubber:
- Withstands temperatures up to 300°F
- Remains fully operable in temperatures as low as -50°F
- Boasts chemical- and water-resistant material
- Features low electrical conductivity
- Adheres to metals with ease
- Offers durable, resilient properties
- Lasts for decades with low wear
While tons of use can wear the rubber faster, it can last up to 50 years with the proper care and with low usage. Put to its limits with extreme circumstances, its lifespan can drop significantly, but it still provides a durable, lasting option for most manufactured products.

Disadvantages of EPDM
While there are tons of great advantages to EPDM rubber, there are a few disadvantages to be wary of when making this material selection. When placed in extremely hot or cold temperatures, EPDM rubber can wear down faster. The rubber unfortunately isn’t flame-resistant either. It has a decent amount of tensile strength, but it falls in the middle of the road for tear resistance. Lastly, it can be damaged by certain solvents, oils, and lubricants, so it should only be used in parts that won’t come into contact with those liquids.
Applications for EPDM
When it comes to fabricated parts, EPDM rubber is great in various industries, especially the HVAC and automotive fields. EPDM is ideal for the following applications:
- Doors & Window Seals
- Electrical Enclosures
- Industrial Machinery & Equipment
- Consumer Products & Appliances
- Outdoor Applications
There are so many uses where EPDM holds up incredibly well and can be manufactured into various sizes and parts depending on the need. With its ability to hold up against weathering, it’s a fantastic option for parts that will spend a lot of time outdoors and are susceptible to the elements.
