What Is Polyester Fiber 12mm?

Polyester Fiber 12mm is a monofilament synthetic fiber made from 100% virgin polyester resin. Cut to a precise 12mm length, it acts as micro-reinforcement that bridges micro-cracks and distributes stress evenly throughout the concrete matrix.

Thanks to its hydrophobic nature and high tensile strength, it maintains performance in harsh alkaline conditions inside concrete, providing long-term durability without corroding like steel fibers. It is an economical, easy-to-mix alternative to traditional reinforcement methods.

Key Benefits of Polyester Fiber 12mm

Polyester Fiber 12mm delivers proven performance advantages that improve both fresh and hardened concrete properties while reducing overall construction costs and time.

Reduces Plastic Shrinkage Cracks by up to 90%

Forms a three-dimensional reinforcement network that controls early-age cracking caused by drying shrinkage and temperature changes.

Improves Impact and Abrasion Resistance

Increases surface toughness, making concrete ideal for industrial floors, pavements, and overlays subjected to heavy traffic and wear.

Enhances Flexural Toughness and Ductility

Absorbs energy and prevents brittle failure, allowing concrete to deform under load without sudden collapse.

Excellent Dispersão and Easy Mixing

Special surface treatment ensures clump-free distribution in the mix, saving time and delivering consistent performance every batch.

Corrosion-Free and Alkali-Resistant

Unlike steel fibers, polyester fibers never rust or degrade in the high-pH environment of concrete, ensuring lifelong reinforcement.

Cost-Effective Alternative to Wire Mesh

Eliminates labor-intensive placement of mesh, reduces formwork damage, and speeds up pouring and finishing operations.

Top 4 Applications of Polyester Fiber 12mm in Construction

Polyester Fiber 18mm is ideal for reinforcing concrete where durability, crack resistance, and structural performance are required. Suitable for new construction, repair, industrial flooring, and prefabricated components.

Pavimentos industriais

Provides superior resistance to heavy forklift traffic, impact loads, and joint spalling while minimizing curling and cracking.

Shotcrete and Tunnel Linings

Increases adhesion, flexural strength, and energy absorption for safer, longer-lasting sprayed concrete applications.

Elementos de betão pré-fabricados

Improves handling strength, reduces breakage during demolding and transport, and enhances final product quality.

Overlays and Pavements

Extends service life of roads, bridge decks, and parking areas by controlling reflective cracking and improving fatigue resistance.
