Polypropylene Fiber Manufacturer

Concrete cracking is one of the most common problems in cement-based products, especially during early curing stages.

Polypropylene fiber for concrete provides three-dimensional reinforcement inside concrete mixtures, helping control plastic shrinkage cracks and improve durability.

LANDU supplies high-strength PP monofilament and mesh fibers manufactured from virgin polypropylene raw materials. With controlled diameter, stable tensile strength, and excellent dispersion, our fibers are widely used in precast concrete, concrete products, and industrial applications.

Why Use Polypropylene Fiber in Concrete?

Reduce Plastic Shrinkage Cracks

Fresh concrete experiences volume changes during hydration and drying.

PP fibers help:

  • Control early-age micro cracks
  • Reduce surface cracking
  • Improve crack resistance during curing

Unlike traditional concrete without fiber reinforcement, PP fiber creates a distributed reinforcement network.

Benefits:

  • Better impact resistance
  • Improved durability
  • Reduced crack propagation

High-strength polypropylene fiber provides effective crack control without significantly increasing concrete weight or affecting workability.

Typical dosage:

0.6-1.2 kg/m³

Actual dosage depends on concrete formulation and performance requirements.
