Polyester fiber

-Prevent ear1y crack of concrete and effectively resist reflection crack

-Prolong the life span

-Increase the crack-resistance in low temperature

-Increase the fatigue-resistance

-Improve the flexibility, seepage-resistance, and stability in water

-Improve the stability in high temperature

Property:

-Small thickness,

-High Tensile Strength 

-Easily scattering,

-Good heat-resistance. It can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance

  for high-tensile concrete.
