What Is Glued Hooked End Steel Fiber 35mm?

Polyester Fiber 18mm is a high-performance synthetic fiber used to improve concrete toughness, durability, and crack resistance. Its uniform dispersion through concrete effectively reduces shrinkage cracks and enhances structural integrity. Made from organic dibasic acid and diol, this fiber offers tensile strength ≥1000MPa, modulus ≥6.0GPa, and a melting point of 160-170℃. Its ideal length and fiber geometry ensure strong bonding within the cement matrix.

Key Benefits of Polyester Fiber 18mm

Polyester Fiber 18mm significantly improves concrete performance by minimizing early shrinkage cracks, increasing tensile strength, and providing long-term structural reinforcement. It is suitable for commercial, industrial, and high-stress construction environments.

Reduces Plastic Shrinkage Cracks: Effectively minimizes early-age cracking caused by water evaporation and temperature variations.

Improves Tensile Strength & Toughness: Enhanced fiber-bridging mechanism increases tensile strength and ductility.

Superior Chemical & Alkali Resistance: Suitable for environments exposed to chemicals, moisture, or harsh weather.

Enhances Durability & Service Life: Reinforces concrete at a microscale, reducing internal weakness. Results in longer service life and reduced maintenance throughout structural use.

Thermal Stability for High-Temperature Conditions: With a melting point of 160-170℃, it reliably performs in areas exposed to heat, repeated thermal change, or industrial processing.

Easy to Mix & Uniformly Disperse: Mixes smoothly into concrete batches without clumping. Ensures consistent fiber distribution across slabs, precast components, and poured structures.

Top 4 Applications of Polyester Fiber 18mm 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.

Flooring & Industrial Slabs

Reduces cracking and increases toughness in warehouse floors, loading zones, road pavements, and high-traffic driveways. Provides long-term resistance to abrasion, impact, and heavy loads.

Infrastructure Construction

Used in foundations, bridges, tunnels, drainage systems, and retaining structures. Helps resist cracking due to settlement and ground movement.

Precast Concrete

Enhances bending strength and ensures better edge resistance for precast pipes, panels, blocks, and beams. Improves product consistency during demolding and transportation.

Residential Construction

Ideal for wall putty, plastering, decorative mortar, and small-scale slabs. Prevents surface cracking and improves hardness and bonding strength.
