EPDM Rubber Seals and Gaskets

EPDM Rubber Seals and Gaskets

EPDM Gaskets is a versatile synthetic elastomer widely used in various industries for seals and gaskets due to its excellent resistance to weathering, ozone, UV radiation, water, steam, and many chemicals. Here’s some key information about EPDM rubber seals and gaskets:

  1. Applications: EPDM rubber seals and gaskets find applications in automotive, construction, HVAC, aerospace, and other industries where sealing against environmental factors is crucial.
  2. Properties:
    • Weather Resistance: EPDM exhibits outstanding weathering properties, making it suitable for outdoor applications where exposure to sunlight, ozone, and temperature fluctuations is common.
    • Chemical Resistance: It resists a wide range of chemicals, acids, alkalis, and polar substances.
    • Temperature Resistance: EPDM can withstand temperatures ranging from -40°C to 125°C (-40°F to 257°F), with some formulations offering even wider temperature ranges.
    • Elasticity and Flexibility: EPDM maintains its flexibility over a wide temperature range, allowing it to conform to irregular surfaces and maintain a tight seal.
    • Electrical Insulation: It has good electrical insulating properties, making it suitable for electrical enclosure gaskets and seals.
    • Tear and Abrasion Resistance: EPDM offers excellent tear and abrasion resistance, prolonging the lifespan of seals and gaskets.
  3. Manufacturing: EPDM seals and gaskets can be manufactured using various methods such as extrusion, molding, or die-cutting, depending on the specific requirements of the application.
  4. Types:
    • Solid EPDM: Solid EPDM seals and gaskets are uniform in composition and are suitable for applications where a consistent seal is required.
    • Sponge EPDM: Sponge EPDM has a cellular structure that provides enhanced compressibility, making it suitable for applications requiring a softer seal or for sealing uneven surfaces.
  5. Common Applications:
    • Automotive: EPDM seals are used in door seals, window seals, trunk seals, and under-the-hood applications.
    • Construction: EPDM gaskets are used in roofing systems, window seals, and HVAC systems.
    • Aerospace: EPDM seals are used in aircraft windows, doors, and other critical sealing applications.
  6. Customization: EPDM seals and gaskets can be customized in terms of shape, size, hardness, and color to meet specific application requirements.

EPDM rubber seals and gaskets offer an excellent combination of durability, flexibility, and chemical resistance, making them suitable for a wide range of sealing applications across various industries.
