Polypropylene engineering fiber, also known as: cracking fiber, PP fiber, engineering fiber. Polypropylene engineering fibers are widely used in industrial, civil construction, mortar crack, waterproof layer, the ground, wall treatment inside and outside the walls; swimming pools, pools, drains and other anti-cracking surface enhancement; reservoirs, dams, docks, ports, hydropower , Airports, bridges, tunnels, high-rise buildings; any mortar or fine aggregate concrete works.

Polypropylene engineering fiber has the following characteristics:

1. Higher strength and elastic modulus, is conducive to the mechanical properties of concrete;

2. With the cement surface grip strong, through the surface treatment, hydrophilic treatment stand ash in the hang, improve the strength;

3. Dispersing excellent, do not hold the mission, to effectively ensure its anti-cracking performance;

4. Fiber chemical stability, strong acid and alkali.

Polypropylene engineering fibers to enhance the function of concrete

1. To prevent mortar, concrete shrinkage cracking;

2. Dry mountain concrete deformation characteristics and toughness;

3. Enhance anti-seepage crack resistance;

4. Improve the impact strength of the wall;

5. Improve peelability, wear resistance;

6. Improve the impermeability, freeze-thaw;

7. Reinforced ribs function

8. To prevent mortar cracking and prevent crack growth
