High Dispersion Anti-Crack Polypropylene Micro Fiber for Concrete and Mortar

High Dispersion Anti-Crack Polypropylene Micro Fiber for Concrete and Mortar

Polypropylene monofilament fiber is an ideal anti-cracking additive for construction. Its core advantages lie in powerful crack control, high toughness and long service life. Resistant to acid, alkali, UV and aging, it keeps stable physical properties long-term.

The fiber disperses fully during mixing,no clumping bringing uniform reinforcement to every part of concrete and mortar. Low water absorption ensures no negative impact on building strength. Light weight and easy operation make it widely applicable for roads, bridges, floors, walls and waterproof projects.

High dispersion polypropylene micro fiber function:

◆High dispersion polypropylene monofilament fiber effectively inhibits microcracks caused by shrinkage of concrete and mortar

◆This anti-crack PP monofilament fiber features excellent dispersion performance without agglomeration during mixing

◆High dispersion monofilament fiber forms 3D reinforcing network to stop crack propagation in cement-based materials

◆Uniformly dispersed PP monofilament fiber improves toughness, impact resistance and durability of concrete

Applying instruction of pp micro fiber concrete fiber :

◆Length of polypropylene  pp monofilament fiber:

Fine aggregate concrete such as mortar is suitable for polypropylene micro fiber length less than 12mm, and coarse aggregate concrete is suitable for concrete above 12mm.

◆Compounding Amount:for resisting the common cracks on surface,0.9kg/m ³fibers to cement mortar are enough.

◆Ratio and mixing requirements:the proportion of cement,sand and aggregate is no need to be changed.Put cement,aggregate,additive and fiber together,then stir after adding enough water and time for stirring can be prolonged for 2-3 minutes in order to make the compound mix completely.Also it can be mixed even with cement and other aggregates in advance,stirring by adding water at worksite before constructing.

Customer evaluation:Our pp micro fiber comes from customer feedback.

Trade show participation：

At Asia Concrete Exhibition 2026, we displayed our core products: polypropylene macro fiber,pp micro fiber,PVA fiber,pp twisted fiber, steel fiber,  Visitors could check sample quality  and material toughness on site. Our technical team offered professional consultation for road base reinforcement, slope protection, concrete reinforcement and other project requirements. Many technical doubts that take months online can be solved efficiently during short face to face talks.

All exhibited items from this show are now available on our website. Please check detailed specifications, sample photos and project cases. Feel free to contact us for pp fiber physical samples and technical proposals for your projects.
