EPDM foam

What is EPDM?

Ethylene Propylene Diene Monomer foam, otherwise known as EPDM foam, is a synthetic rubber used for a multitude of applications. Its exceptional properties make this rubber ideal for outdoor areas and hot weather. It stands up well to difficult weather, such as hot and cold temperatures, direct sunlight, ozone, alkalinity and acidity, oxygenated solvents, and oxidation. However, it is not compatible with most hydrocarbons, oils, white oil, gasoline, and halogenated solvents. On the other hand, it has great thermal flexibility, and noteworthy resistance to water and steam, which are other important features of EPDM.

EPDM offers compatibility, waterproofing, and excellent insulation. EPDM rubber is used for sealing, making gaskets, and crafting membranes and diaphragms. EPDM is frequently employed when a component requires the ability to restrict fluid passage while still being pliable. It can also be used to provide padding or flexibility. Although EPDM has adequate tensile strength, its pliability makes it inappropriate for rigid items such as cogs, shafts, and structural beams.

  • High tear resistance
  • Medium density
  • Elongation to moderate tearing
  • High resistance to UV and ozone
  • High flexibility and reversibility
  • Moderate resistance to direct heat
  • Waterproof, sound insulation, heat and cold
  • Usable temperature range -40 to +105 degrees Celsius

EPDM Applications

EPDM foam stands out from other materials due to its superior properties and quality, making it a desirable choice for a range of applications and sectors. EPDM is a highly rated material that is suitable for a wide range of uses and is extensively used in the automotive industry for various vehicle components. Its outstanding strength and other advantageous qualities make EPDM foam the perfect material for automotive use. It is mainly used for sealing up windows and doors, reducing vibration, providing better insulation, and making hoses and washers.

EPDM foam has proven to be very resistant to UV radiation, ozone, alkaline substances, water, heat, steam, and weather conditions; however, it has been found to have lesser resistance to some oil-based products. Some of these substances include grease, petroleum derivatives, hot tar, and vegetable and mineral oils, which should be avoided.

  • Aerospace industry
  • Construction industry (door and window sealant, etc.)
  • Automotive industry (types of washers, door and window sealants, vibration reduction and insulation, etc.)
  • Railway and subway
  • All kinds of industrial washers (for sealing and insulation)
  • Shipbuilding industry (insulation of ship hull, types of washers, etc.)

EPDM foam stands out from the rest due to its capability to resist ozone, light, water, chemicals, and fire. Key features of this foam include closed-cell structure, resilience (elasticity), and recoverability.

In case you encounter any issues or need help with the use of this foam in your industry, please reach out to our design and development department for technical consultation.

Different EPDM Products

We can produce and supply EPDM foam in sheet form, with each sheet having its unique abilities depending on its use. EPDM foam can be purchased in sheet form with dimensions of 1000 by 2000 centimeters and a thickness of 32 millimeters, sheet sizes of 1720 by 1100 centimeters and a thickness of 32 millimeters, and sheet sizes of 1450 by 1060 centimeters and a thickness of 32 millimeters.

Compared to non-saturated rubbers such as natural rubber, SBR, or neoprene, EPDM exhibits much better resistance to light, heat, and ozone. EPDM can be designed to handle temperatures greater than 150 degrees Celsius and remain in great condition over the years. Depending on its formulation, this material can remain flexible even at -40 degrees Celsius.

Foamiran specializes in creating many different types of EPDM sheets with various dimensions and thicknesses to suit the individual needs of each customer.

What is an EPDM Foam Sheet?

EPDM foam sheets are a type of foam sheet known as Ethylene Propylene Diene Monomer. The popularity of these sheets among consumers in industries like automotive, refrigeration, and packaging of impact-resistant goods is due to the qualities they possess. Closed-cell foam is their construction material, and it provides a high resilience, similar to rubber, and also renders them resistant to UV, light, water, acids, bases, and even extreme temperature changes.

Consumers have been drawn to the EPDM foam sheets developed by the R&D unit of the Foamiran group in Iran and they can purchase them. Sections of the EPDM sheet surface are referred to as “EPDM sheet”. EPDM sheets usually come in black with a width of 1 meter, a length of 3.3 meters, and a thickness ranging from 2 to 15 millimeters.

Foamiran can create EPDM sheets in various lengths, widths, and thicknesses to fulfill the individual needs of customers.

EPDM Foam Sheet Applications

EPDM foam is an ideal electrical insulator, making it a great selection for electrical insulation in specific industries. It displays excellent resistance to creep and leakage current, which makes it a great choice when those traits are necessary for the desired outcome. EPDM is employed for steam, industrial piping systems, and power plants. Closed-cell foam forms a reliable insulation layer, stopping the flow of air, water, and liquids.

The EPDM sheet with closed cells is used to make water-resistant solutions for a variety of vehicle items that need to be sealed. The doors, windows, hoods, and trunk of the vehicle should be sealed. If needed, this insulation can stop noise caused by friction and freezing due to cold temperatures and snow. Other than waterproofing and sealing for cars, EPDM sheeting can be used for making different parts for the automotive industry, like grommets, pedal pads, and other items.

Frequently Asked Questions

What is EPDM foam?

EPDM foam is a type of closed-cell synthetic rubber foam made from copolymers of ethylene, propylene, and a small amount of diene monomer. This chemical composition gives it unique physical and chemical properties, making it highly resistant to harsh environments.

What are the most important features of EPDM foam?

Due to its outstanding properties, EPDM foam is an excellent choice for industrial applications and challenging environments:

  • Excellent weather resistance: It is particularly resistant to UV radiation, ozone, sunlight, and adverse weather conditions, which contributes to its very long lifespan.
  • Water and moisture resistance: Thanks to its closed-cell structure, it does not absorb water, making it ideal for sealing applications.
  • High thermal resistance: It can be used in a wide range of temperatures (typically from -40 to +105 degrees Celsius).
  • Good chemical resistance: It is resistant to many weak acids, alkalis, salts, and chemicals. (However, it has low resistance to petroleum-based substances, gasoline, and oils.)
  • Shock absorption and vibration damping properties: It is effective for damping vibrations and reducing impact.
  • Thermal and acoustic insulation: It helps reduce the transfer of heat and sound.
  • High flexibility and resilience: It retains its shape even after repeated compression.
  • High tear resistance: It has good mechanical durability.
What are the applications of EPDM foam in various industries?

Due to its excellent features, EPDM foam has a wide range of applications:

  • Automotive industry: Door and window seals, gaskets, engine and cabin insulation, and vibration-damping components.
  • Construction industry: Window and door seals, rooftop waterproofing, and insulation for pipes and HVAC systems.
  • Shipbuilding and marine industries: Insulation, sealing, bumpers, and flotation parts (due to its resistance to saltwater).
  • Electronics industry: Gaskets and protective pads for insulation and to prevent moisture and dust ingress.
  • Mechanical industries: Washers, gaskets, and seals in industrial machinery.
  • Sports surfaces: Used in some outdoor flooring or underlayers that require weather resistance.
What is the main difference between EPDM foam and EVA or PE foams?

EPDM foam is primarily made of synthetic rubber, whereas EVA and PE foams are plastic-based. This chemical difference makes EPDM significantly more resistant to weathering, ozone, high temperatures, and certain chemicals. In contrast, EVA and PE may offer different levels of flexibility or shock absorption. For sealing and gasketing applications in harsh environments, EPDM demonstrates superior performance.
