Polymer Fibers – Concrete Microfiber by MTC Concrete

TM MTC Concrete offers high-quality polypropylene fibers (microfiber) for effective dispersed concrete reinforcement. Fibers measuring 12 mm in length and 18–22 μm in diameter distribute evenly throughout the concrete mix, significantly reducing the risk of cracking during the early stages of curing.

Product Overview

Polypropylene microfiber is an innovative monofilament fiber ranging from 2 to 18 mm in length (most commonly 12 mm) with a diameter of approximately 18–22 μm. One kilogram contains up to 250–500 million fine fibers, ensuring truly dispersed reinforcement throughout the concrete.

Key Advantages

Reduces the formation of cracks — shrinkage, plastic, and hydration — through uniform fiber distribution.
Improves mechanical performance: increases tensile and flexural strength, impact resistance, and wear resistance by up to 30–52%..
Resistant to aggressive environments: non-reactive with acids or alkalis, providing long-term durability.
Increases freeze-thaw and water resistance by 30–40%..
Cost-effective alternative to steel mesh, easy to use, and safe for concrete equipment.

Specifications & Dosage

Fiber lengths: 2, 3, 4, 6, 12, 18 mm – depending on contractor needs;
Standard length: 12 mm (diameter 18–22 μm);
Recommended dosage: 0.6–0.9 kg/m³ — for dry mixes and screeds, up to 2.5 kg/m³ — for industrial floors, pavement slabs, and hydraulic structures.

Applications

Screeds, self-leveling and industrial floors.
Paving tiles, decorative concrete elements.
Facades, tunnels, airfield slabs, hydraulic and civil engineering structures.
Dry construction mixes, shotcrete, foam concrete.

Certification & Quality

The fibers comply with European standards and undergo strict quality control according to ISO international certifications.
