Macro Synthetic Fibre Description
The fibres are Made of Polypropylene.
Macro Synthetic Fibre Advantages:
✅ Disruptive Cost Advantage
Only 3-10kg/m³ dosage required (vs. steel fiber’s 25-40kg/m³), delivering 30%+ material cost savings while reducing transportation and storage expenses.
✅ Smart Dispersion Technology
Patented water-soluble film packaging (PP50): Drop the entire box into the mixer, dissolves in 5 seconds for clump-free fiber dispersion, boosting construction efficiency by 50%.
✅ Engineered Crack Resistance
Textured wave surface + 400MPa tensile strength, significantly enhancing concrete impact resistance (ASTM C1018) and shrinkage control (ASTM C157), achieving industry-leading crack prevention standards.
✅ All-Rounder for Harsh Environments
100% polypropylene material with acid/alkali corrosion resistance (ASTM D7508) and 160°C thermal stability, perfectly suited for demanding applications like mines, ports, and chemical plants.
✅ Eco-Safe Certification
Zero water absorption, heavy-metal-free, certified by ISO 9001/14001, and compliant with LEED green building standards.
Polypropylene fibers in concrete Features
Ø
Provides good impact,fatigue,shrinkage control and ductility in all grade concretes.
Ø
Cost saving,Is easier to use,to disperse
and safe to handle.
Ø
Can be used in highly corrosive circumstance.
Ø
The
surface has been embossed,which greatly improves the cohesive force between fibres and concrete,and also boosts shrinkage resistance and crack resistance.
Ø
The toughness of macro synthetic fibre
is less stronger than steel fibre.But test has shown slabs on grade and pre-cast concrete predominately require a dosage rate of between 25kg-40kg of steel fibres per cubic meter, in comparison,using between 3kg-10kg of macro synthetic fibre
per cubic meter of concrete.
Synthetic fibres achieve greater strength and ductility in the matrix.
Estimating Data
The dosage rate is dependent on the application however the minimum dosage range
is 3kg/m3-10kg/m3.
Typical Application
Shotcrete,
and engineering industries,
concrete project,like being used in base,ground, bridge, dam, especially where relatively large-scale deformations may be expected,
such as in mining engineering environment.

How should the fibre be used--
PP50
The fibres are wrapped with water-soluble film and uniquely packaged in paper boxes.Then just throw the whole boxes of fibres into the concrete mixture, the boxes and film then dissolve within seconds, leaving the fibres to disperse evenly throughout the mixture.
