EPDM’s flexibility and wide operating temperature range contribute to its versatility. The specific properties can be adjusted through the manufacturing process, offering tailored solutions for different needs.
| Feature | Description |
|---|---|
| Ozone Resistance | Excellent; significantly better than many other rubbers. |
| Heat Resistance | High; maintains its properties at elevated temperatures. |
| Weathering Resistance | Excellent; resists degradation from sunlight and other environmental factors. |
| Chemical Resistance | Good; resists many acids, alkalis, and polar solvents but not non-polar solvents. |
| Tensile Strength | Moderate; lower than some other types of rubber. |
| Flexibility | High; easily bends and conforms to shapes. |
| Temperature Range | Wide; can operate in a broad range of temperatures. |
Types of EPDM Rubber
The properties of EPDM can be modified during the manufacturing process. This leads to several types of EPDM rubber, each suited to specific applications. These variations primarily involve differences in the level of cross-linking, the addition of fillers, and the incorporation of other polymers. The choice of EPDM type depends on the required balance of properties, such as flexibility, durability, and resistance to specific chemicals. Different types find their niche in various industries and applications.
| Type | Description | Applications |
|---|---|---|
| General Purpose | Standard EPDM; balances cost and performance. | Gaskets, seals, automotive parts, hoses |
| High-Temperature | Formulated for use at higher temperatures. | Applications requiring resistance to high heat |
| Oil-Extended | Contains oil to improve processability and reduce cost. | Applications where cost is a primary concern |
| Peroxide-Cured | Cured using peroxide, providing superior heat resistance and chemical resistance. | High-performance applications requiring exceptional durability |
| Specialty Grades | Tailored to meet specific requirements, such as high purity or specific chemical resistance. | Applications with unique demands, such as medical or aerospace applications |
