What is EPDM: A Versatile, Cost-Effective Rubber Part Solution
When you need a rubber material that offers excellent resistances to weather, heat, and other factors without breaking the bank, EPDM grommets, gaskets, tubing, and other parts may be the answer you need.
EPDM – also known as ethylene propylene diene monomer – is an extremely versatile material used in a variety of applications, from automotive products to HVAC parts. This type of rubber also acts as a less expensive alternative to silicone, as it can endure weather conditions, abrasion, and other challenges for long periods of time with proper use.
Due to its combination of physical durability, performance capabilities, and cost, investing in custom EPDM parts can save you time and money on a wide range of applications. These benefits have made EPDM a go-to material for many parts.
What Does EPDM Rubber Come From?
EPDM is a synthetic rubber derived from the polymerization of ethylene, propylene, and certain other alpha-olefin comonomers. The first example of EPDM dates back to Nobel Prize winner Karl Ziegler.
The German scientist discovered that he could product a strong, flexible compound while conducting polymerization experiments. The new material was first introduced to the U.S. market in the early ‘60s, quickly gaining popularity in the roofing and other industries for it’s beneficial properties and cost-effective price point.
One of the major reasons why EPDM caught on as a rubber compound was because it marked the first elastomer developed that combined good heat resistance, ozone resistance, excellent mechanical properties over a wide temperature range, and good chemical stability. While other materials have been created to address greater temperature needs and other performance factors, EPDM has maintained popularity and is ideal for many uses.

EPDM Benefits and Advantages
- Resistance to UV exposure, ozone, aging, weathering, and many chemicals – great for outdoor applications.
- Stability in high and low temperatures – a general purpose EPDM material can be used in an environment where the temperature range is from -20⁰F to +350⁰F (-29⁰C to 177⁰C).
- Offers excellent resistance to highly acidic substances and corrosive materials, making it ideal for parts that encounter intermittent or even regular exposure to caustic elements.
- Features low toxicity and odor levels, making EDPM rubber a safer option for applications meant for human interaction.
- Low electrical conductivity.
- Steam and water resistant.
- Can be fabricated in a variety of ways, which includes custom molding, extruding, sheeting, and die cutting.
- Long-term part lifespan allows for fewer replacement parts, saving money in the long run.
