What are the Properties of EPDM Rubber?

EPDM (Ethylene Propylene Diene Monomer) rubber is a versatile synthetic elastomer known for its superior durability, flexibility, and weather resistance. In comparison to other elastomers like nitrile, EPDM rubber is much more superior in its outdoor resistance properties. The material is formed by combining ethylene, propylene, and diene monomers through vulcanization, creating a chemically stable polymer that can withstand harsh environments while maintaining structural integrity.

One of the standout properties of EPDM rubber is its excellent resistance to ultraviolet (UV) radiation, ozone, and oxygen. This makes it ideal for outdoor applications as it does not degrade under prolonged exposure to sunlight. Its resistance to weathering and aging ensures a long operational lifespan, even in challenging conditions. Additionally, another essential feature of EPDM that makes it suitable for outdoor applications is its moisture resistance. Closed Cell EPDM foam, with its tightly-knit air pockets, prevents permeation of water and other liquids, offering an absorption rate of less than 5%. This moisture resistance is particularly beneficial in applications requiring waterproofing, such as roofing membranes and weatherstripping.

In terms of cold and heat, EPDM rubber sheets are highly resistant to extreme temperatures, with EPDM temperature rating typically ranging from -40°F to +200°F. This wide temperature rating makes it suitable for applications such as weatherproof seals, membranes, and industrial gaskets which are subjected to extreme climates.

EPDM rubber chemical resistance is another crucial property to note. It exhibits excellent compatibility with polar substances such as water, alcohol, and alkalis while being less resistant to non-polar substances like oils and hydrocarbons. This makes EPDM rubber sheets ideal for industrial applications involving water-based or alkali-based chemicals, as they can resist deterioration and maintain structural integrity over time.

The mechanical properties of EPDM rubber also stand out as it has a high tensile strength, low compression set, and excellent flexibility, allowing it to absorb shocks and vibrations effectively. Solid EPDM rubber sheets and rubber strips, for example, are commonly used in heavy-duty applications where durability is essential. Meanwhile, the closed cell EPDM foam variant offers compressibility and resilience, making it suitable for sealing applications.

In terms of adaptability, EPDM rubber types range from solid to sponge, each serving different needs. Solid EPDM is dense and durable, and it is widely used in applications requiring robust resistance to weathering, ozone, and UV exposure. On the other hand, EPDM foam strips and sheets offer compressibility and sealing properties, making them ideal for creating seals in HVAC systems, weatherstripping for doors and windows, and vibration-damping pads. The material also comes in various EPDM sizes, catering to specific industrial requirements.

Open Cell EPDM vs Closed Cell EPDM

Solid vs Cellular EPDM

Solid EPDM Rubber Sheets and Rolls
Solid EPDM rubber is a dense, bubble-free material that lacks the air pockets found in its sponge-like counterparts. This is what you think of when you think a dense un-sponge like rubber. This form of EPDM rubber offers exceptional resistance to extreme weather, UV rays, and ozone, making it ideal for outdoor applications. This rubber material’s elasticity allows it to withstand high pressure and repeated movement without losing its shape or performance. Solid EPDM is often used where strength, reliability, and impermeability are critical, such as in heavy-duty seals for industrial machinery or as a barrier against moisture and harsh chemicals. Its robust performance across diverse environments ensures it is a go-to choice for industries requiring long-term solutions.

Cellular EPDM Rubber Sheets
Cellular EPDM has two categories, open cell EPDM rubber and closed cell EPDM rubber. Both rubber types feature a compact structure with air pockets, which provide excellent insulation, lightness, and water resistance. This type of EPDM is particularly suited for applications that require a high level of compressibility and flexibility, such as gaskets, seals, and marine equipment. The closed cell design also enhances its thermal insulation properties, making it ideal for HVAC systems, automotive weatherstripping, and other environments where preventing the ingress of air, water, or sound is essential. Its lightweight and flexible nature makes it easy to handle and install, yet it remains durable enough to resist wear and tear over time.

Solid vs. Closed Cell and Open Cell EPDM Rubber
Solid EPDM is dense and durable, providing maximum strength, weather resistance, and chemical compatibility, making it ideal for all your heavy-duty operations. This product is heavier (weighs about 1lbs per sq. ft). These applications can range anywhere from industrial seals and membranes to automotive components. The solid structure ensures it is impermeable to air and water, offering long-lasting performance in demanding environments. Closed cell EPDM is comparatively much lighter and weighs 0.15lbs per sq. foot and features sealed air pockets within its structure, providing excellent insulation and water resistance. This type of EPDM is effective in applications where thermal, acoustic, and moisture barriers are needed. Closed-cell EPDM is comparatively lighter, and features sealed air pockets within its structure, which are not interconnected. Unlike open-cell EPDM, where air pockets form a network that allows the passage of water and air, the closed-cell structure prevents such connectivity. This design makes closed-cell EPDM effectively waterproof while also providing excellent insulation and resistance to moisture. Its unique structure is ideal for applications requiring thermal, acoustic, and moisture barriers, ensuring reliable performance in environments where exposure to water or humidity is a concern. Open cell EPDM is an porous material that consists of large air pockets, easily visible to the naked eye. This product is lighter and weighs about 0.12lbs per sq. foot in a 1/4″ thickness. The interconnected air pockets allow air, water, and sound to pass through. This makes it ideal for cushioning, padding, and soundproofing applications, such as in automotive interiors and packaging. While it might lack the impermeability of solid and closed-cell EPDM, it compensated with superior breathability, and shock absorption.

Open Cell Rubber – EPDM – 39″ x 78″

• Operating temperature range from -40° F to 160° F
• Easy to roll up for transportation and storage purposes

Made for the Outdoors: Open cell EPDM is the perfect foam sheet for any application where the presence of sunlight and other elements is present. UV and ozone have a tendency to harm certain types of materials after a while, but that is not the case with EPDM foam. It is designed to have a longer lifespan when exposed to the elements.

Excellent Compressibility: This EPDM rubber foam is among the most compressible products currently available. The cellular composition of this open cell rubber material is the secret behind its ability to compress. The cell structure is composed of tiny air pockets that have gaps in between them. When force is applied to the surface of the EPDM sponge, these air pockets will close in on themselves. The source of the pressure will also not face any resistance due to the soft nature of open cell sponge. The EPDM foam sheet will maintain its compressed form as long as the object applying the pressure remains.

Fast Recovery: The open cell EPDM has the ability to revert back to its original shape after compression. When the source of pressure is removed from the open cell rubber sheet’s surface, the air pockets within its cellular composition will revert back to their original shape. This helps the EPDM rubber foam maintain a working lifespan suitable to long-term use in applications that require constant compression.

How Long Does EPDM Rubber Last?

One key advantage of EPDM rubber is its lifespan, which can vary depending on several factors. These include EPDM rubber application, environmental exposure, and the specific EPDM rubber type used.

Environmental factors such as exposure to UV rays, temperature fluctuations, and moisture heavily influence EPDM rubber lifespan. Fortunately, EPDM rubber has excellent chemical resistance, making it a great choice for harsh environments. For example, rubber strip EPDM is commonly used as seals for doors or windows in automotive applications. These strips are exposed to intense sunlight, rain, and oils. Despite these harsh conditions, EPDM rubber seals maintain their integrity for many years, typically lasting between 20 and 50 years, depending on thickness and the level of exposure.

In roofing, closed cell EPDM foam is widely used for its waterproofing properties. The foam’s structure prevents water absorption, helping EPDM rubber last longer in exposed settings, such as flat roofing systems, with a lifespan of 25 to 40 years. Its resistance to ozone and UV rays also contributes to its long-lasting performance, even under extreme weather conditions.

EPDM temperature rating also influences its longevity. EPDM rubber is known to withstand extreme temperatures from -40°F to +200°F without losing its flexibility or structural integrity. This makes EPDM rubber ideal for applications exposed to wide temperature fluctuations. Whether it is in high-temperature automotive applications or cold environments like refrigeration, EPDM rubber can maintain its performance for many years. For example, EPDM foam strip used in vehicle gaskets need to remain flexible to form effective seals regardless of weather changes. EPDM temperature rating ensures these strips continue to perform well in hot summers and freezing winters, contributing to the rubber’s lifespan.

Another factor contributing to the lifespan of EPDM rubber is its chemical resistance. EPDM is highly resistant to many chemicals, oils, and solvents, which makes it an excellent material for applications in the chemical industry, automotive manufacturing, and construction. For instance, EPDM rubber is used in gaskets and seals in fuel systems, where exposure to gasoline and other chemicals is inevitable. Its resistance to degradation from these substances means it can perform reliably for years, even in demanding environments.
