EPDM Gaskets

EPDM gaskets are a type of rubber gasket known for their excellent weather resistance, chemical resistance, and thermal stability. Here’s a breakdown of EPDM gaskets:

  1. Material Composition: EPDM gaskets are made from a synthetic rubber compound consisting primarily of ethylene, propylene, and a diene monomer. This composition gives EPDM its unique properties, including resistance to ozone, weathering, UV exposure, and a wide range of chemicals.

  2. Properties:

    • Weather Resistance: EPDM gaskets are highly resistant to weathering, ozone, and UV exposure, making them suitable for outdoor applications where exposure to sunlight and harsh weather conditions is a concern.
    • Chemical Resistance: EPDM gaskets offer excellent resistance to a wide range of chemicals, including acids, bases, alcohols, ketones, and automotive fluids. This chemical resistance makes them suitable for use in various industries, including automotive, aerospace, HVAC, and plumbing.
    • Temperature Resistance: EPDM gaskets have good thermal stability and can withstand temperatures ranging from -40°C to 120°C (-40°F to 248°F), depending on the specific formulation. They are commonly used in applications where moderate temperature resistance is required.
    • Flexibility and Elasticity: EPDM gaskets are flexible and elastic, allowing them to conform to irregular surfaces and maintain a reliable seal, even under compression or thermal cycling.
    • Electrical Insulation: EPDM rubber has good electrical insulation properties, making it suitable for use in electrical enclosures and other applications where electrical insulation is required.
  3. Manufacturing Process: EPDM gaskets can be manufactured using various methods, including compression molding, injection molding, and extrusion. The choice of manufacturing method depends on factors such as the complexity of the gasket design and the required production volume.

  4. Applications: EPDM gaskets find applications in a wide range of industries and applications, including automotive, aerospace, construction, HVAC, plumbing, and electrical. They are commonly used for sealing applications such as doors, windows, enclosures, pipe connections, and roofing systems.

  5. Customization: EPDM gaskets can be customized to meet specific application requirements, including size, shape, hardness, and color. They can also be fabricated with adhesive backing for easy installation.

  6. Environmental Considerations: EPDM rubber is considered an environmentally friendly material because it does not contain harmful substances like heavy metals or halogens. Additionally, EPDM is recyclable and can be reused or repurposed at the end of its service life.

Overall, EPDM gaskets offer a combination of weather resistance, chemical resistance, temperature resistance, flexibility, and elasticity, making them a versatile sealing solution for various industrial and commercial applications.

Peroxide-cured EPDM gaskets

Peroxide-cured EPDM gaskets are crafted using a curing method involving peroxide as a cross-linking agent, enhancing the material’s properties. This process increases heat resistance, compression set resistance, and improves the overall mechanical performance of the gaskets. Ideal for applications demanding higher temperature resilience and durability, such as automotive engines, peroxide-cured EPDM gaskets offer enhanced sealing capabilities in challenging environments.

FDA approved EPDM gaskets

FDA-approved EPDM gaskets are tailored to meet strict food safety standards, ensuring they’re safe for contact with food and beverages. Composed of EPDM rubber compounded with FDA-compliant materials, they exhibit excellent resistance to temperature variations (-40°C to 120°C), chemicals, and compression set. Widely employed in food processing equipment, packaging machinery, and storage containers, these gaskets provide reliable sealing without jeopardizing product purity. Customizable in size, shape, and hardness, they cater to diverse application requirements while adhering to stringent food safety regulations.
