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.

◆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.
| 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. |
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.
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.
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.
Colour: available in white — great when appearance matters.
Lengths: choose from 38, 48, 50, 54, 60 mm, etc.
Sold in 1 kg or 0.9 kg water-soluble bags for easy handling and eco-friendly disposal.
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.

Traditional concrete wall construction faces a long-standing set of operational challenges. Labor-intensive steel mesh installation consistently slows down project timelines. Over time, moisture penetration creates severe spalling risks as internal steel begins to corrode.
Traditional secondary reinforcement relies heavily on welded wire mesh. This approach demands significant manual labor. It frequently suffers from improper placement on job sites. Worse, it rarely prevents early-stage plastic shrinkage cracking.
Rising costs of heavily polymer-modified asphalt (PMA) and Stress Absorbing Membrane Interlayers (SAMI) are forcing pavement engineers to seek alternative mechanical reinforcement strategies.
Uncontrolled foam in industrial processes doesn't just look messy. It causes severe equipment cavitation and significantly reduces usable tank capacity. It also slows down production throughput and introduces critical defects into finished products.
Modern highway and industrial road construction faces massive pressure. Project owners demand aggressively accelerated timelines. They also expect extended lifecycle durability from every pavement slab.
Concrete contractors and specifying engineers face mounting operational challenges today. Unpredictable steel costs frequently squeeze tight project margins. Placing traditional welded wire mesh demands intensive manual labor and slows down pour schedules.
The concrete reinforcement industry is undergoing a massive shift. Engineers and contractors are rapidly moving away from labor-intensive traditional steel like rebar and wire mesh. Advanced engineered polymers now offer a smarter, highly efficient alternative for modern builds.
Managing foam generation remains a massive hurdle in food, beverage, and packaging production. Excess foam severely reduces processing throughput. It causes messy spillovers on facility floors. You must control this rapid macrofoam expansion without violating strict food-contact safety regulations.
