Polypropylene crude fiber is also called plastic steel fiber and imitation steel fiber. It is made of polypropylene as the main raw material and refined by a special production process. Its surface is corrugated, with good dispersibility and adhesion to the cement matrix. It is mainly used to replace metal grids and steel fibers in concrete panel structures.

Product parameters：

Name: Polypropylene crude fiber

Density: 0.91 g/cm3

Melting point: 170 ℃

Tensile strength: ≥450MPa

Shape: bamboo-shaped, wavy

Elongation at break: 8%-10%

Length mm: 30-60mm

Color: white, transparent

Standard dosage: 2-20kg/m3

General dosage: 2.5kg/m3

Application areas:

Mainly used in reinforced and partially reinforced concrete structures such as highway pavements, bridge decks, airport pavements, aprons, docks, industrial floors, warehouse floors, and spraying projects.

The biggest characteristics of polypropylene crude fiber are high strength, high modulus, low elongation, and no pollution. It can replace steel fiber for crack resistance and reinforcement of cement concrete. It is specially used for concrete reinforcement fiber for roads, railways, tunnels, and culverts.

Product advantages:

Polypropylene crude fiber has high strength, corrosion resistance, high temperature resistance, strong chemical stability, strong grip with concrete, anti-aging, anti-wind erosion, acid and alkali resistance, anti-magnetic and anti-rust... It plays a more three-dimensional role in reinforcement and bridging. It is easy to construct and does not damage the equipment.

It not only maintains the bonding, high temperature stability, fatigue durability, and low temperature crack resistance of the original traditional concrete fiber, but also greatly improves the workability and dispersibility of the fiber in concrete, and can more evenly bear the main load of the entire concrete structure.
