STOPFIBER 200

A compound containing pure PTFE fibres, expanded PTFE microspheres and synthetic lubricants. It can be used as a “zero leak” seal on valves, pumps and mixers with peripheral speed no greater than 8 m/sec. It can be successfully used in cryogenic applications and up to a maximum temperature of 260°C with almost all fluids, even the most aggressive ones. It requires little maintenance, reduces the maintenance times of rotary plants and once applied needs no replacements, simply additions. It does not stain nor colour, and does not lose volume. Density: 610 cm3/kg.

Applications

Stopfiber is a line of products with an extremely advanced sealing system designed for pumps, valves and rotating shafts in general, which, when inserted in a housing, surround the rotating shaft like a single sleeve which is extremely well lubricated and thereby completely eliminate any point of excessive pressure. Correctly used, Stopfiber products guarantee long life to the entire equipment, even previously damaged equipment. Their regular replacement guarantees a secure, efficient seal with minimum leaks. Containing no asbestos, they do not cause wear and resist high temperatures, aggressive chemical products and high peripheral speeds.
