    Introduction of PTFE fiber
     Mar 22, 2020|View:591

    PTFE fiber is a kind of synthetic fiber made from polytetrafluoroethylene (PTFE) by spinning or making films and cutting or fibrization. PTFE has a relatively large molecular mass, with the low reaching hundreds of thousands, the high reaching more than 10 million, and generally millions. The crystallinity of PTFE polymer is generally 90-95%. Due to the strong polarity of fluorine atoms, the polymer exhibits extremely stable physicochemical properties. Its long-term use temperature in 200-260 degrees, melting temperature of 327-342 degrees; It's still soft at minus 100 degrees; It also has the best aging life and the smallest friction coefficient among plastics.

    PTFE fiber

    PTFE fiber characteristics

    Corrosion resistance, low friction coefficient, good chemical stability, good weather resistance and deflection resistance

    PTFE fiber features

    1. High temperature resistance: operating temperature up to 250℃

    2. Low temperature resistance: when the temperature drops to -195℃, 5% elongation can be maintained

    3. Resistance to corrosion: resistance to most chemicals, good chemical inertness

    4, weather resistance: with the best aging resistance

    5, high lubrication: the friction coefficient is very low

    6. Acid-base resistance: insoluble in strong acids and organic solvents

    7. oxidation: resistance to strong oxidant corrosion

    8. Non-toxic: with physiological inertia

    PTFE fiber applications

    PTFE is mainly used as filter material for waste incinerator and coal boiler, non-metal bearing, plastic filler for reducing friction and sewing wire. High temperature dust filter bag made of PTFE fiber has been widely used as the filter bag of municipal waste incinerator.
