Types of EPDM Rods
Different types of EPDM rods cater to specific applications. The variations often involve the addition of fillers or modifications to the base EPDM material. This affects the final properties of the rod. These differences can significantly impact the rod’s performance and suitability for specific use cases.
The following table compares common types of EPDM rods:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Solid EPDM Rod | A standard EPDM rod with consistent density throughout. | High strength, durability, good for high-pressure applications. | Less flexible than sponge EPDM. |
| Sponge EPDM Rod | EPDM with a porous structure, offering better shock absorption and sealing capabilities. | Flexibility, good for sealing and vibration dampening, lightweight. | Lower strength than solid EPDM, may absorb fluids. |
| Filled EPDM Rod | EPDM with added fillers like carbon black (for increased strength) or other materials (for specific properties). | Enhanced strength, wear resistance, or other tailored properties depending on filler. | May compromise flexibility or other properties depending on the filler used. |
| Color-Coded EPDM Rod | EPDM rods available in various colors for easy identification and tracking in applications. | Easy identification, simplifies inventory management. | Color may affect certain properties slightly. |
The choice of EPDM rod type depends on the application requirements.
