While Ethylene Propylene Diene Monomer, or more commonly known as EPDM, gasket properties stem from its synthetic and inorganic composition, these industrial rubber gaskets are created for nature! EPDM rubber and gasket products are designed to withstand the great outdoors! Whether to help homes weather out storms or to protect equipment from harsh weather, EPDM gaskets are durable and reliable products designed to thrive where many gaskets deteriorate – outdoors. These industrial rubber gaskets can also be made with impact resistant so they can withstand abrasive environments. Used in hundreds of applications, EPDM is one of the most popular gasket materials for anything from automotive industries to refrigeration or electoral insulation markets.
Closed Cell Rubber – EPDM
Closed Cell Rubber – EPDM
- Temperature Range: -40° F to 200° F
- Durometer rating of 15 Shore C
- Sheets available in size of 39″ by 78”
- Perfect for use in indoor or outdoor applications
High Compressive Strength: Closed cell rubber is a bit different from its open cell counterpart in terms of compressive strength. While open cell sponge rubber can rebound back to its original shape very quickly, closed foam rubber sponge takes a bit longer to do so. This allows the closed cell EPDM sponge rubber to handle high- pressure applications at a better rate, making it more durable.
Perfect for the Outdoors: The excellent ability of this closed cell rubber to operate in the outdoors is all thanks to the compound of EPDM rubber in its structural makeup. It has an excellent level of resistant to both UV rays and ozone. Outdoor factors like UV and ozone may not damage a material immediately, but they can definitely degrade a material over time. The EPDM compound in this sponge rubber allows it to remain exposed to the elements for extended periods of time. This is the primary reason why EPDM material is a popular elastomer to use in applications such as window sealing on vehicles and homes.
Developed in the 1950’s, EPDM was designed specifically for the Middle East because of the large range of temperature fluctuations that occur in the desert. Not only did EPDM have to resist permanent deterioration, but it also had to remain flexible and durable regardless of the temperature. Able to withstand such harsh conditions, EPDM has definitely proved itself as the material to beat for any outdoor applications. While this rubber material is chemically designed to be well-adjusted to outdoor settings, it does not give up any of the beneficial properties of natural rubber. EPDM remains flexible with good tensile strength. Here are the most important reasons for buying EPDM rubber and gasket products:
- Engineering asked for it. Enough said!
- Great weather resistant qualities
- Affordable price point
- Stocked in a wide variety of gauges
- Can be produced in an assortment of durometers
- Can be die-cut, waterjet or hand-cut based on tolerance concerns and budget
- Sold in blended (less expensive) or 100% EPDM versions
EPDM – Commercial Grade – 60A
EPDM – Commercial Grade – 60A
- EPDM rubber with a smooth finish
- A black weather resistant rubber that is ideal as an outdoor liner or pad
- EPDM material is in stock in 1/16″, 1/8″, 3/16″, 1/4″, 3/8″, 1/2″ thickness
- A blend of Ethylene Propylene Diene Monomer (EPDM rubber) and SBR
- This sheet rubber weighs about 1-1/4 lbs. per square foot in 1/8″ thickness
Excellent Industrial Sheet Rubber: EPDM rubber has adequate elastic and pliable qualities. The material has a durometer of Shore 55-65A but on average, has a Shore 60A measurement. A Shore A scale measures the hardness of the rubber. For example, a soft pencil eraser has a durometer of Shore 20A. Although higher than an eraser, the durometer of EPDM still maintains a good amount of flexibility for all of your necessary projects. In addition, EPDM rubber has a minimum elongation of 300%.
Popular Gauges: Rubber-Cal understands that some gauges are in higher demand than others. Therefore, the most popular gauges can usually be found in stock, ready for customers. This includes a range of eight different gauges to choose from. Custom thickness and widths are available upon request, though non-standard sizes will have large minimum orders. A Rubber-Cal representative can assist you in exploring customization options. With so many choices, you’re bound to find the perfect size of EPDM material.
Closed Cell Rubber – EPDM – 39″ x 78″
Not only do these products retain helpful and useful properties of natural rubber, these man-made elastomers actually improve upon natural rubber material. This synthetic rubber is actually able to retain high elasticity and flexibility despite cold temperatures. Oftentimes other rubbers will become brittle and crack in colder temperatures. EPDM rubber remains effective in a temperature range of -54 degrees Celsius to 150 degrees Celsius. Of course the latter is contingent on the actual EPDM rubber and gasket product EPDM is available in a variety of blends, durometers, and tensile strengths. In other words one EPDM part may not be anything like another just because they both have EPDM content. For example it is used an industrial rubber and gasket seal where steam is present, which is generally outdoor. Regardless of the damaging effects of steam, EPDM gaskets will not deform permanently and will remain in place to hold a vacuum seal. As mentioned before, this is one of the few rubbers that can remain outside because most rubbers are attacked by UV or ozone molecules and become damaged. EPDM gasket material is one of the few rubbers that can repel ambient heat and ozone rays effectively. Rain or sunshine, these seals will continue to work because, on top of being heat resistant, they are also waterproof. This makes them ideal for electrical applications as well because they insulate the electrical currents from water to avoid any dangerous situations.
Unfortunately, EPDM gaskets can’t have it all; they are vulnerable to most oils and concentrated acids. Luckily this can be somewhat remedied by applying a specialty coat to increase the chemical resistance of EPDM. These are not, however, ideal for applications involving oil even after coating the material. It is better to keep EPDM gasket material where it belongs – outside.
Whether for electrical, waterproof, or extreme temperature situations, EPDM rubber and gasket products are the top product for thousands of applications. They are durable and flexible seals that can withstand almost every environment due to their ability to resist damage through UV, ozone, and temperature fluctuations. EPDM gasket material is unsurpassed in its resistance to weathering despite harsh environments and remains one of the most recommended materials used for gasketing needs.
