EPDM Rubber Seals and Gaskets

EPDM rubber seals and gaskets are widely used in various industries for their excellent properties and versatility. Here are some key aspects to know about them:

  1. Material Composition: EPDM rubber is a type of synthetic rubber characterized by its high resistance to weathering, ozone, UV exposure, and extreme temperatures. It’s made from ethylene, propylene, and a diene comonomer.
  2. Chemical Resistance: EPDM rubber exhibits good resistance to many chemicals, acids, and alkalis, making it suitable for applications where exposure to such substances is expected.
  3. Temperature Range: EPDM gaskets maintains its properties across a wide temperature range, typically from -50°C to +150°C (-58°F to +302°F). This makes it suitable for both indoor and outdoor applications.
  4. Weather Resistance: EPDM rubber is highly resistant to weathering, ozone, and UV radiation, making it ideal for outdoor applications such as automotive weatherstripping, roofing materials, and outdoor seals.
  5. Sealing Properties: EPDM rubber seals and gaskets offer excellent sealing properties, providing a reliable barrier against moisture, air, dust, and other environmental elements. They are commonly used in automotive, aerospace, construction, and industrial applications.
  6. Flexibility and Elasticity: EPDM rubber is known for its flexibility and elasticity, allowing it to conform to irregular surfaces and maintain a tight seal even under dynamic conditions.
  7. Water Resistance: EPDM rubber has low water absorption properties, which helps prevent water penetration and ensures long-term sealing performance in wet environments.
  8. Electrical Insulation: EPDM rubber possesses good electrical insulation properties, making it suitable for applications where electrical conductivity needs to be minimized.
  9. Applications: EPDM rubber seals and gaskets find applications in a wide range of industries, including automotive (door seals, window seals, hose seals), construction (window and door seals, roofing membranes), HVAC (pipe gaskets, duct seals), and industrial (tank seals, machinery gaskets).
  10. Manufacturing Process: EPDM rubber seals and gaskets can be manufactured using various methods, including compression molding, injection molding, extrusion, and die-cutting, depending on the specific requirements of the application.

EPDM rubber seals and gaskets are preferred for their durability, weather resistance, sealing properties, and versatility across diverse industrial applications.
