PVA Fiber Properties and Characteristics

  1, High strength and low elongation: superior mechanical properties

  2, Acid and alkali: the loss of strength is low even it is under high temperature a long time.

  3, Lightfastness: Under long-term sunlight, the fiber strength loss rate is lower than other fibers.

  4. Corrosion resistance: The fiber is buried in the ground for a long time without being moldy, rot, or insects.

  5, Anti-crack anti-seepage: distributing the fiber chaotic in the concrete (mortar) can effectively prevent the occurrence of cracks, development and improve the waterproof and impermeability.

  6. Dispersion: The fiber does not stick, and it is well dispersed in water and has a good affinity with cement.

  7. Shock and Seismic: effectively absorb impact energy and improve earthquake resistance.

  8, antifreeze, anti-fatigue: the stress caused by the temperature difference can improve the ability of antifreeze, anti-fatigue
