HOW PP FIBER WORKS
From Fiber Dispersion to Better Durability
Uniformly dispersed PP fibers create a three-dimensional reinforcement network, effectively reducing cracks and extending the service life of concrete structures.
01
Even Dispersion
Uniformly distributed in concrete and mortar.
02
Micro Reinforcement
Forms a three-dimensional fiber network.
03
Crack Reduction
Controls plastic and drying shrinkage cracks.
04
Longer Service Life
More durable structures with lower maintenance costs.

Frequently Asked Questions
Polypropylene fiber is used as secondary reinforcement in concrete and mortar to help control plastic shrinkage cracking, improve toughness, and enhance long-term durability. It is widely used in concrete slabs, flooring, precast products, renders, plaster, shotcrete, and tunnel linings.
PP fiber disperses throughout the concrete or mortar matrix and helps distribute internal stresses more evenly. This can reduce the formation and development of small cracks caused by plastic shrinkage, drying, temperature changes, and other stresses.
Polypropylene fiber is mainly used to improve crack resistance, toughness, impact resistance, and durability rather than significantly increase compressive strength. Its performance depends on the fiber specification, dosage, concrete formulation, and application conditions.
MIKEM polypropylene fiber is available in lengths ranging from 3 mm to 20 mm, with customized lengths available according to different construction applications and formulation requirements.
MIKEM polypropylene fiber has a tensile strength of ≥500 MPa and is manufactured from 100% virgin polypropylene, providing stable reinforcement performance in cement-based systems.
When properly selected and dosed, polypropylene fiber can be incorporated into concrete and mortar without significantly affecting normal application performance. However, excessive dosage or poor dispersion may influence workability, so formulation testing is recommended.
Yes. PP fiber can be used in various cement-based dry-mix formulations, including plaster, render, repair mortar, and other construction materials where improved crack resistance and durability are required.
No. Polypropylene does not rust like steel reinforcement. Its resistance to moisture and many common chemicals makes PP fiber suitable for applications where corrosion resistance is important.
