Best Selling PP Polypropylene Staple Micro Fiber 12mm For Fine Aggregate Concrete Projects
Polypropylene Fiber is an anti cracking fiber used in the plastic stage of concrete and mortar to prevent cracking. It can effectively prevent plastic cracking of mortar and plays a role of "secondary reinforcement" in concrete and mortar; Polypropylene short fibers are made of high-strength polypropylene fibers, which undergo special processes such as chemical modification, physical modification, anti-static, and UV resistance. They have the characteristics of small diameter, large specific surface area, and uniform dispersion. They form a three-dimensional disordered structure inside concrete and mortar, and can lock in internal moisture in the mortar, preventing and reducing micro cracks caused by tip effects in the mortar, Reducing the generation of early stress and preventing cracks caused by early evaporation of water, thereby hindering the formation of large-scale cracks.

Feature & Function of Polypropylene Fiber
1.Easy to be dispersed in mortar or concrete and no agglomeration, it can guarantee the property of crack resistance effectively.
2. Easy to be used: No need to change the proportion of mortar, just put the fibers into the mortar mixture and stir for a moment after adding water.
3. It with fine economic property: The equivalent diameter of PP Fiber monofilament is only 0.02-0.03mm, so the ratio of diameter and surface area is high and on the basis of crack resistance, it can reduce the amount (to about 0.6-0.9kg/m3 ).
4. Easy to plaster: As the great number of thin fibers spread into mortar evenly, the plastering is much easily and this can improve the binding strength between surface and base.
