|---|---|---|
| Hardness (Shore A) | ° | 75 ± 5 |
| Tensile Strength | MPa | ≥10 |
| Elongation at Break | % | ≥200 |
| Specific Gravity | g/cm³ | 1.11 |
| Compression Set | % | ≤70 |
| Ozone Resistance | Pass/Fail | Pass |
| Low-Temp Brittleness | Pass/Fail | Pass |
Types of EPDM 75 and Their Differences
While the core composition remains consistent, variations exist within EPDM 75 formulations. These differences arise from the addition of fillers, additives, and processing techniques. These variations impact the final properties of the material. For example, some EPDM 75 might be formulated for enhanced heat resistance, while others prioritize flexibility or specific chemical resistance. The choice of EPDM 75 type depends entirely on the intended application. The suppliers listed on hongjusilicone.com offer a range of EPDM products highlighting this variability.
| Type of EPDM 75 | Key Characteristics | Typical Applications |
|---|---|---|
| Standard EPDM 75 | Balanced properties, good general performance | Gaskets, seals, weather stripping |
| High-Temperature EPDM 75 | Enhanced heat resistance | Automotive parts, industrial applications requiring high heat |
| Chemical-Resistant EPDM 75 | Improved resistance to specific chemicals | Chemical processing equipment, storage containers |
| High-Flexibility EPDM 75 | Increased flexibility and elongation | Applications requiring significant movement or deformation |
