EPDM Rubber Seals and Gaskets

EPDM Gaskets is a popular material for seals and gaskets due to its excellent resistance to weathering, ozone, UV exposure, and temperature extremes. Here’s a breakdown of its properties and common applications:

  1. Weather Resistance: EPDM rubber can withstand exposure to harsh weather conditions, making it ideal for outdoor applications such as automotive seals, window seals, and roofing membranes.
  2. Chemical Resistance: It has good resistance to many chemicals, acids, and alkalis, enhancing its suitability for various industrial sealing applications.
  3. Temperature Resistance: EPDM rubber exhibits excellent heat resistance, retaining its properties across a wide temperature range from -50°C to 150°C (-58°F to 302°F).
  4. UV Resistance: Its resistance to ultraviolet radiation makes it a preferred choice for outdoor sealing applications where exposure to sunlight is common.
  5. Electrical Insulation: EPDM rubber has good electrical insulating properties, making it suitable for use in electrical enclosures and cable insulation.
  6. Flexibility and Elasticity: It remains flexible even at low temperatures, ensuring a tight seal over a wide range of conditions. It also has good elasticity, allowing it to recover its shape after compression.
  7. Water Resistance: EPDM rubber is impermeable to water and moisture, making it suitable for use in sealing applications where water resistance is critical, such as in plumbing seals and gaskets.

Common applications of EPDM rubber seals and gaskets include:

  • Automotive seals: Door seals, window seals, hood seals, trunk seals, and windshield seals.
  • Industrial gaskets: Pipe gaskets, flange gaskets, valve seals, and pump seals.
  • Building and construction: Roofing membranes, window seals, and expansion joint seals.
  • Electrical enclosures: Seals for electrical cabinets, control panels, and junction boxes.
  • HVAC systems: Seals for air conditioning units, refrigeration systems, and ductwork.

EPDM rubber seals and gaskets are valued for their durability, longevity, and reliability in various demanding environments.
