Stopfiber 200

A compound containing pure PTFE fibers, expanded PTFE microspheres, and synthetic lubricants. It functions as a "zero leak" seal for valves, pumps, and mixers at peripheral speeds up to 8 m/sec, and is effective from cryogenic temperatures up to 260°C with most fluids, including aggressive ones. It requires minimal maintenance, reduces downtime, and needs only occasional additions rather than full replacements. It is non-staining, retains its volume, and is non-abrasive.
