Material Notes:

Special, pure white compound with PTFE blended for improved dynamic performance. Has excellent chemical resistance, 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 shorter term to 310°C (590°F). Recommended for use in the semiconductor industry. Do not use any Perlast ® grade with molten alkali metals.
