Main Applications


For airport,concrete road,bridge,Improve concrete crack resistance, like concrete road, bridge, airport road and factory floor which strictly require cracking resistance.


For bridge, airport,concrete roadImprove permeability of concrete, like walls of tunnels, mines, roofs and reservoir projects with special construction, river courses and dams, and so on.


For concrete road,bridge, airportImprove durability of concrete and aging resistance.


For oil drilling platformImprove the impact, folding resistance, fatigue resistance, and seismetic resistance.


For chimney,refractoryImprove the fire performance of concrete


With polypropylene as its raw material, this fiber is produced by special technology, the products have net-like structure with many fiber monofilaments, when the fiber is put into the concrete, the horizontal structure in fiber monofilament can be destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net like structure will fully stretch, thus the concrete is reinforced by a great number of polypropylene fibers.


Good dispersion,no fascicles,strong toughness and strength.

Prevent concrete cracks,like concrete road,bridge,airport and grade leve.

Improve permeability resistance of concrete,walls of tunnels,mines,roofs and reservoir projects with special construction.

Improve concrete freezing-thawing resistance.

Improve impact resistance of concrete,folding resistance,fatigue resistance,seismic performance.

Improve the durability of the concrete and aging resistance.

Improve the fire performance of concrete.
