Polypropylene Fiber

The polypropylene fiber, or geofiber, is meticulously manufactured from polypropylene, organic and inorganic materials through special production process, and it is mainly intended to reinforce the mechanical properties of concrete, thus extending the service life.

Our structural polypropylene fiber forms a 3D random network in concrete so as to prevent micro crack growth at early ages of concrete setting, thereby enhancing the breaking strength, crack resistance and anti-permeability of concrete. So, this crack resistant fiber offers perfect resistance to crack, permeation, abrasion and heat for concrete and mortar projects.
1. Crack Resistance: The polypropylene fiber reduces non-structural cracks generated when concrete is in its plastic stage.
2. Anti-Permeability: Our synthetic concrete fiber is a rigid waterproof material that could avoid water permeation in concrete.
3. Dosage: 0.6-1.8kg/m3 (typical value: 0.9kg/m3)
