PP Fiber 3mm, 6mm, 9mm, 12mm

Polypropylene short fiber is a kind of strong bundle monofilament fiber made from polypropylene with a unique production process.

Small diameter and a large specific surface area; it has good dispersibility in cement-based materials, resistance to acid, alkali, salt and other chemical corrosion, high melting point, and non-toxic.

It can be widely used in various mortars, underground waterproof works, walls, floors, cement, basements, roads and bridges.


Performance of PP Fiber in dry powder mortar or concrete

Anti-crack function
Improve anti-infiltration performance
Improve anti-freezing and thawing
Improve toughness and anti-shock
Improve durability
Improve fire resistance

 Adding it into concrete mortar can effectively control the micro cracks caused by solid plastic shrinkage, dry shrinkage, temperature change and other factors of concrete mortar, prevent and slow the formation and development of cracks, and greatly improve the crack resistance, impermeability, impact resistance and seismic resistance of concrete.

1. It is evenly dispersed in the mortar to form a three-dimensional disordered structure inside, and can lock the moisture inside the mortar, with strong grip and wrapping force;

2. It is not easy to agglomerate in mortar or concrete, which effectively ensures the play of its crack prevention performance. It is convenient to use, without changing the mortar ratio. Put the fiber into the mortar mixture and add water to mix evenly;

3. In the concrete, the wear resistance, impermeability, freeze-thaw resistance of the concrete are improved, and the reinforcement protection function is enhanced;

4. The fiber has stable chemical properties, strong acid and alkali resistance, and can be used in any project.
