Introduction
When selecting materials for outdoor or automotive applications, EPDM rubber is frequently the top choice. Engineers and manufacturers rely on EPDM rubber because of its exceptional ability to withstand harsh environmental conditions. In this article, we will explore why EPDM rubber is the industry standard for weather resistance and how it benefits your projects.
EPDM rubber (Ethylene Propylene Diene Monomer) is a high-density synthetic rubber known for its versatile applications. It is characterized by a stable, saturated polymer backbone, which gives it superior resistance to heat, oxidation, and ozone compared to natural rubber.
The primary advantage of EPDM rubber is its longevity. It does not crack or degrade easily when exposed to UV rays or ozone. According to standards set byASTM International, EPDM maintains its properties even in extreme temperature fluctuations.
| Type | Hardness (Shore A) | Temperature Range |
| Standard EPDM | 40 – 90 | -50°C to +150°C |
| Peroxide Cured | 50 – 80 | -55°C to +160°C |
Environment: If the part is exposed to oil, EPDM is not suitable (use NBR instead). EPDM is strictly for water, steam, and weather.
Compression Set: For sealing, choose a grade with a low compression set to ensure the seal rebounds after pressure.
| Industry | Common Usage | Key Benefit |
| Automotive | Weatherstripping | Prevents water/noise entry |
| HVAC | Gaskets/O-rings | Resists steam and heat |
Q: Can EPDM rubber be used with petroleum oils?
A: No, petroleum oils will attack and swell EPDM.
Q: What is the life expectancy of EPDM?
A: In outdoor applications, it can last over 20 years without significant degradation.
Choosing EPDM rubber ensures your products withstand the test of time and weather. For high-performance sealing solutions, selecting the right manufacturer is critical.
