- UV Resistance: EPDM exhibits exceptional resistance to ultraviolet radiation, ensuring long-lasting performance even in harsh outdoor conditions.
- Ozone Resistance: It is highly resistant to ozone, a major cause of rubber degradation, making it suitable for applications exposed to atmospheric ozone.
2. Heat Resistance
- High-Temperature Tolerance: EPDM can withstand high temperatures without significant degradation, making it suitable for applications in hot environments.
3. Chemical Resistance
- Resistance to Oils and Fuels: EPDM is resistant to many oils and fuels, making it ideal for automotive and industrial applications.
- Water Resistance: It has excellent water resistance, making it suitable for outdoor and marine applications.
4. Flexibility and Durability
- Flexibility: EPDM maintains its flexibility over a wide temperature range, ensuring proper sealing performance in various conditions.
- Durability: It is highly durable and resistant to abrasion, tearing, and other forms of mechanical stress.
5. Electrical Insulation
- Good Electrical Properties: EPDM has good electrical insulating properties, making it suitable for applications where electrical insulation is required.
