PTFE Fiber for High-Temperature Filter Media
PTFE fiber offers unmatched chemical resistance and long-term stability under continuous temperatures up to 250°C. As a core material for premium filter felts, it ensures high-performance dust collection in the most aggressive industrial environments.
Description
PTFE (Polytetrafluoroethylene) fiber is widely recognized as the ultimate solution for extreme industrial filtration. Thanks to its inert chemical structure, PTFE fiber maintains dimensional stability and filtration precision even in environments where acid, alkali, and oxidizing gases are present.
It is especially suited for waste incineration plants, chemical processing, non-ferrous metallurgy, and coal-fired boilers, where standard fibers (polyester, PPS, or aramid) degrade rapidly. PTFE fiber ensures longer service life, reduced maintenance frequency, and stable filtration efficiency, delivering exceptional long-term value.
