Material Notes:

A special black perfluoroelastomer compound with PTFE blended for improved mechanical performance. Excellent steam resistance and mechanical properties. Extremely low outgassing properties. Applications: Particularly suitable for dynamic applications which require long-term exposure to temperatures in excess of 260°C (500°F) and short term to 310°C (590°F). Do not use any Perlast ® grade with molten alkali metals.
