Key Features

  • Strong mechanical strength
    Through the needle-punching process, PPS fibers are intertwined to form a stable three-dimensional structure. This process not only helps to fix the position of the fibers and improves the mechanical strength of the felt, but also enhances its tensile and wear resistance.

  • High-temperature resistance
    PPS needle felt has excellent high-temperature resistance and can operate stably for a long time in high-temperature environments above 160°C. Even if the instantaneous temperature reaches 180°C, it can adapt to the dust removal needs of high-temperature flue gases such as boilers and power plants.

  • Chemical stability
    It has good corrosion resistance to acidic and alkaline gases and can maintain stable filtration performance in corrosive gas environments.

  • Dust removal effect
    PPS needle felt has excellent filtration performance and can efficiently capture and separate solid particles in high-temperature flue gas, thereby improving the flue gas purification effect.
