Descriptions of EPDM Foam Gaskets

EPDM foam gaskets are made from a synthetic rubber material known for its:

  • Weather Resistance: Resistant to UV rays, ozone, and extreme weather conditions.
  • Temperature Tolerance: Can withstand temperatures from -40°C to +120°C (-40°F to +248°F).
  • Elasticity and Compression Set: Maintains shape and sealing properties under compression.
  • Chemical Resistance: Resistant to water, acids, alkalis, and polar solvents.

Applications 

EPDM gaskets are ideal for sealing in the following industries:

  1. Automotive:
    • Door and window seals.
    • Engine compartment gaskets.
    • Weather stripping for vehicles.
  2. HVAC:
    • Sealing ductwork and air conditioning units.
    • Insulation for pipes and vents.
  3. Construction:
    • Window and door seals.
    • Roofing and waterproofing applications.
  4. Industrial:
    • Sealing for machinery and equipment.
    • Gaskets for electrical enclosures.

Benefits 

  • Durability: Long-lasting performance even in harsh environments.
  • Flexibility: Conforms to irregular surfaces for a tight seal.
  • Eco-Friendly: Can be recycled and is free of harmful chemicals.
  • Cost-Effective: Reduces maintenance and replacement costs due to its longevity.
