Polymer Twisted Fibres Product Overview


Twisted Fibres are engineered to enhance concrete performance. Designed as a cost-effective alternative to steel fibers, they form a 3D reinforcement network within concrete matrices, mitigating microcracks caused by thermal fluctuations, plastic shrinkage, and drying stresses. The twisted bundle structure ensures optimal dispersion and bonding, delivering superior crack resistance and durability.

What is the function of Polymer Twisted Fibres in concrete? 

Crack control

     Helps cut down on plastic and drying shrinkage cracks in floors,     

     industrial slabs, and pavements.

Durability Enhancement

     1. Improves freeze–thaw resistance in cold climates, helping        

         prevent scaling and spalling.

    2. Increases abrasion resistance for high-traffic areas like 

       warehouses and garages.

◆ Workability

    1. Works with standard concrete mixes — usually no mix adjustments needed.

    2. For even dispersion, use a twin-shaft horizontal mixer; mix at least 5 minutes per m³.

Polymer Twisted Fibres data advantages

Feature Details
Save money

About 50% cheaper than steel fibers — more budget left for what matters.

Corrosion Resistance Holds up in damp or chemically harsh places like basements and kitchens.
Lightweight Design

At just 0.91 g/cm³, it reduces the weight of your structure.

Chemical Stability

Not bothered by oil, detergents, or common industrial chemicals.

Easy Handling

Dry fibers mix right in — no special gear, no fuss.

Polymer Twisted Fibres Installation Guidelines

Mixing

      First, add the fibers to the aggregates and mix for about 2 minutes. Then add the cement and water and keep mixing.

      If you're using higher doses (for example, 5.5 kg/m³), extend mixing to 7–10 minutes to ensure the fibers spread evenly.

Use with mesh fibers

       In some projects, you can pair this with polypropylene mesh fiber (0.9 kg/m²) — it helps control cracking and keeps hairline cracks 

       from showing up.

Cost & long-term value

      Save money: swapping 47 kg/m³ of steel fibers for 5.4 kg/m³ of XRT-PLW provides the same reinforcement at roughly half the cost.

       Better long-term: it lasts longer and cracks less, so you'll spend less on repairs down the road.

Customization & availability

      Color: available in white — great when appearance matters.

      Lengths: choose from 38, 48, 50, 54, 60 mm, etc.

 Packaging

Sold in 1 kg or 0.9 kg water-soluble bags for easy handling and eco-friendly disposal.

Polymer Twisted Fibres Safety & Compliance

Non-Toxic: PP is inert and environmentally safe.

Certifications: Complies with ASTM C1116 and ISO 9001 standards.
