EPDM Rubber

Excellent resistance to weather, ozone and environmental conditions for outdoor applications

View Specifications

EPDM Rubber (Ethylene Propylene Diene Monomer) is a synthetic elastomer recognized for its exceptional resistance to weather, ozone, severe environmental conditions and excellent low-temperature performance.

With a Shore A hardness of 60-65 points and a wide operating temperature range from -20°C to 145°C, EPDM is the preferred material for outdoor applications requiring durability and aging resistance.

EPDM Rubber Detail

Superior Resistance Properties

EPDM Rubber stands out for its unique properties for outdoor applications:

  • Excellent weather resistance and aging
  • Superior ozone resistance and UV radiation
  • High elongation (400% minimum) and flexibility
  • Excellent alcohol resistance and chemical products
  • Good low-temperature performance
  • Excellent vibration and impact absorption

These properties make it indispensable in construction, automotive, industrial applications, and any outdoor environment exposed to severe weather conditions.
