| 71 (FFKM) | 72 | black | -20 | 250 | FFKM is characterized by excellent chemical and thermal stability with consistent elasticity and is extremely low in outgassing. These favorable material properties combined in one product are not achieved by any other synthetic rubber on the market. However, perfluoro rubber is relatively expensive due to the technically very complex manufacturing process and is therefore not a mass-produced plastic. | Kalrez®Perlast® |
