EPDM Rubber
Excellent resistance to weather, ozone and environmental conditions for outdoor applications
View SpecificationsEPDM Rubber (Ethylene Propylene Diene Monomer)
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.
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.
