    Synthetic micro fiber : polyvinyl alcohol fiber (PVA Fiber)
    Date:2025-07-28 Clicks:6次

    High-strength and high-modulus polyvinyl alcohol fiber (PVA Fiber)


    Polyvinyl alcohol fiber(PVA Fiber) has the characteristics of high strength and high modulus. It can effectively control the generation and development of non-structural cracks such as plastic shrinkage of concrete and cement mortar, effectively hinder the segregation of aggregates, hinder the formation of settlement cracks, improve the impermeability and impact resistance of concrete, increase the toughness and wear resistance of concrete, thereby extending the life of the building.


    Effect in concrete:

    It can improve the plastic shrinkage cracks of cement mortar and concrete before curing.

    Increase the toughness of cement mortar and concrete.

    Improve the intrinsic quality of cement concrete mortar.

    Reduce maintenance costs.

    Extend the service life of the project.


    Product performance:

    1. Appearance: slightly yellow.


    2. High strength and low elongation.


    3. Acid and alkali resistance: Under long-term high temperature, the strength loss is lower than other fibers.


    4. Light resistance: Under long-term sunlight, the fiber strength loss rate is much lower than other fibers.


    5. Corrosion resistance: The fiber will not mold, rot, or be eaten by insects when buried underground for a long time.


    6. Dispersibility: The fiber does not stick together, disperses well in water, and has good affinity with cement.



    Main uses:


    1. Cement reinforcement material The fiber has high strength and good dispersion performance, is pollution-free and non-toxic, and has the characteristics of corrosion resistance, insect resistance, and sunlight resistance. It can be widely used in cement products and road construction, water conservancy projects, etc.


    (1) Replace asbestos to make high-strength cement products.


    (2) Can be used in road construction, especially high-grade highway construction.


    (3) Filament bundles can be used in water conservancy project construction, replacing steel bars as tensioning belts.


    2. Can be made into high-strength ropes, safety nets and high-strength industrial textiles.


    3. Can be made into tire cords, rubber reinforcement materials, used for conveyor belts, fire hoses
