Brief Introduction


Polypropylene staple fiber(PP Fiber) is high-strength bundled monofilament fiber made from polypropylene. Add to mortar or concrete, it will efficiently reduce micro-cracks, which were caused by solid plastic shrinkage, heat shrinkage and temperature changes. Further to prevent the crack’s occur and expansion. greatly improved crack resistance, impermeability, impact resistance and aseismicity of concrete.

 
Application Performance

1, To improve the fire resistance of concrete and mortar;
2, To better the durability and aging resistance of concrete and mortar;
3, To improve the impact resistance, folding resistance, fatigue resistance and aseismicity of concrete and mortar;
4, To improve the freezing-thawing resistance of concrete and mortar;
5, To improve the impermeability of concrete and mortar;
6, To prevent cracks in concrete and mortar.
