White Polypropylene Pp Bundle Macro Polymer Twisted Fibres for Floor

Hot sale! In concrete, adding polymer-twisted fibres can effectively mitigate temperature changes and plastic and drying shrinkage-induced microcracks, thereby preventing and controlling crack formation and development and improving the concrete's crack resistance, permeability resistance, and impact resistance.

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.

Why pick white polymer twisted fibres instead of black/grey synthetic fibre? 

Pure virgin material indicator

Our white polymer twisted fibres are made from new clear PP pellets for a natural white appearance. Black/grey fibres usually contain recycled plastic and carbon filler. White tone proves no impurities, with stable chemistry and strong alkali resistance.

Clean decorative finish

White polymer twisted fibres blend well with light concrete, leaving no dark spots after polishing. Perfect for floors, decorative overlays and precast ornaments.

Fast on-site quality check

You can easily see even dispersion or exposed white polymer twisted fibres during construction for quick inspection and touch-up.

◆Identical core performance

The white colour only improves visual handling. It does not affect anti-crack, crack-bridging or durability, same as coloured polymer fibres.

Selection tip:

Use white polymer twisted fibres for pale polished floors and decorative precast parts; choose grey fibres if you need visual concealment.

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 environments, such as basements and kitchens.
Lightweight Design

At just 0.91 g/cm³, it reduces your structure's weight.

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 fibres 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 fibres spread evenly.

Use with mesh fibres

       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 fibres 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

      Colour: 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.

RFQ

1. Q: Will fibre concrete crack?

     A: White polymer twisted fibres eliminate early plastic shrinkage hairline cracks and slow down dry shrinkage cracking. It cannot 

          completely prevent large structural cracks caused by overloading, foundation settlement, or severe temperature differences.

2. Q: How long does fibre concrete last?

     A: Mixed with qualified white polymer twisted fibres, concrete effectively blocks microcracks and water penetration. Its service life 

          can be extended by 20–40% compared with ordinary concrete under the same environment. Service lifespan also depends on 

          raw materials, construction craft and external erosion conditions.

3. Q: Do you need rebar in concrete if you use polymer fibre?

    A: White polymer twisted fibres only control micro shrinkage cracks. For structural load-bearing parts such as beams, columns and 

        large slabs, rebar is still mandatory. Fibres serve as secondary reinforcement rather than a full replacement for steel rebar.

4. Q: Will white fibres show on the surface or affect polishing?

     A: Proper dosage and finishing avoid fibre protrusion. For polished floors, use recommended finisher steps; white fibres often blend 

          well with light-coloured concrete.

5. Q: Packaging and bulk supply options?

     A: Supplied in bags/cartons or boxed OEM packaging; bulk orders available with lead times. Contact supplier with project volume 

         for quotes and logistics.
