MIKEM supplies monofilament polypropylene microfibers for concrete, mortars, screeds, plasters, and selected construction applications.
Our fine PP fibers are designed to support plastic shrinkage crack control, fresh-mix cohesion, and fiber dispersion when used with appropriate mixing procedures.
We help customers evaluate fiber specifications, application requirements, sample options, and commercial supply arrangements.
Monofilament Polypropylene Fiber is a lightweight synthetic micro-reinforcement material made from fine, individual polypropylene filaments. When incorporated into concrete and mortar, these fibers distribute throughout the cementitious mixture, helping control early-age cracking and improve the overall performance of construction materials.
With excellent resistance to moisture and alkaline environments, monofilament PP fiber provides a practical reinforcement solution for different concrete and mortar systems.
MIKEM manufactures monofilament polypropylene fiber with controlled specifications, flexible fiber lengths, and customized packaging to meet the needs of construction material manufacturers, contractors, and distributors.

Monofilament PP fiber offers multiple benefits for cement-based materials, from early-age crack control to improved fresh mix performance.
Helps minimize plastic shrinkage and settlement cracks, supporting better concrete surface quality during early curing.
Promotes fresh mix stability and helps reduce bleeding and segregation during concrete placement.
Helps improve the toughness and impact resistance of suitable concrete and mortar formulations.
Unlike metallic reinforcement materials, polypropylene fibers do not rust and offer good resistance to alkaline environments.
Contributes to improved abrasion resistance in suitable fiber-reinforced concrete applications.
Fine monofilament fibers can be distributed throughout concrete and mortar with an appropriate mixing process, supporting consistent reinforcement.
APPLICATIONS
Monofilament polypropylene fiber is suitable for a wide range of concrete and cement-based applications where shrinkage crack control, mix cohesion, and material durability are important.
Used in warehouse floors, factory flooring, commercial buildings, and industrial concrete slabs to help control early-age shrinkage cracking.
Suitable for concrete roads, sidewalks, driveways, and pavement systems, helping improve crack control during the early curing stage.
Incorporated into precast panels, concrete pipes, pavers, and other factory-produced concrete components to support crack control and handling performance.
Helps improve cohesion and minimize surface cracking in cement-based renders, floor screeds, wall plasters, and repair mortars.
Used in sprayed concrete and underground construction systems to help improve mix cohesion and reduce rebound in suitable formulations.
Provides supplementary micro-reinforcement in selected concrete pavement and deck applications where early-age crack control is required.

For proper product storage:
Monofilament polypropylene fiber is a synthetic micro-reinforcement material made from fine, individual polypropylene filaments. It is commonly incorporated into concrete and mortar to help control shrinkage cracking and improve fresh mix cohesion.
It is widely used in concrete floor slabs, industrial flooring, roads, pavements, precast concrete, shotcrete, cement-based mortars, screeds, and plasters.
When distributed throughout concrete, the fibers help restrain the development of small cracks caused by plastic shrinkage and settlement, particularly during the early stages of curing.
MIKEM offers fiber lengths ranging from 3 mm to 20 mm, with customizable options according to specific application and formulation requirements.
No. Conventional monofilament polypropylene microfibers are primarily used for supplementary reinforcement and early-age crack control. They should not be considered a direct replacement for structural steel reinforcement unless a specific engineered system has been tested and approved for that purpose.
Yes. It can generally be incorporated into concrete formulations containing commonly used admixtures, such as plasticizers and water reducers. Trial mixing is recommended to confirm compatibility and workability.
The dosage depends on fiber specifications, concrete mix design, and application requirements. Customers should refer to the product technical data sheet and conduct appropriate mix trials to determine the suitable dosage.
Choose a manufacturer that provides consistent raw materials, controlled fiber diameter and length, reliable tensile strength, current technical data sheets, and batch quality documentation. The manufacturer should also offer samples, formulation guidance, customized fiber lengths, suitable packaging, and dependable supply. MIKEM supports product evaluation and customized monofilament polypropylene fiber solutions for different concrete and mortar applications.
