Technical specifications of polypropylene fibers

Polypropylene coarse fiber,also known as plastic steel fiber or imitation steel wire   fiber,is refined through special production processes using polypropylene and polyeth- ylene as the main raw materials.Its surface is rough,its contour is clear,and it has good dispersibility and adhesion with the cement matrix.The product has both the functions of steel fibers and the advantages of synthetic fibers,mainly used to replace welded
metal grids and steel fibers in concrete panel structures.Polypropylene coarse fiber is    an iron filled product that fills the gap between steel fibers and polypropylene fibers.Its performance is similar to that of shear steel fibers.The surface of this fiber is rough and  uneven,with a diameter of about 0.8mm.It is a new type of reinforcement and toughen- ing material.When the fiber content is high,the fiber has a significant effect on the early crack resistance of concrete,which can replace steel fibers or steel wire mesh,increase   the toughness of concrete,improve the ability to resist temperature stress or burst.

Application area

Mainly used in concrete panel structures,reinforced and locally reinforced concrete struc- tures,and shotcrete engineering,carbon reinforced steel bars,specifically used for concrete
reinforcement in highways,railways,tunnels,and culverts,are single filament fibers processed and processed using polymer fiber materials through special processes.Its biggest characteris- tics are high strength,high elongation,low elongation,and pollution-free.Can replace steel fibers for crack resistance enhancement in cement concrete It not only maintains the bonding,    high-temperature stability,fatigue durability,and low-temperature crack resistance of traditional concrete fibers,but also greatly improves the workability and dispersion offibers in concrete,
and can more uniformly bear the main load of the entire concrete structure;It has high strength, corrosion resistance,high temperature resistance,strong chemical stability,strong grip strength of concrete,anti-aging,wind  erosion   resistance,acid  and  alkali  resistance,magnetic  and  rust resistance,etc.It  plays  a  more  three-dimensional  role  in  reinforcing  and  bridging.It  is  easy  to construct and does not cause damage to equipment.
