NOVASTAR Top Polypropylene Fiber Manufacturer – Crack Resistance Experts

What is Polypropylene Fiber(PP Fiber)?

Polypropylene fiber, also known as anti-crack fiber, PP fiber, building material fiber, and microfiber, is a synthetic material widely used in mortar and concrete. Polypropylene fiber is a bundled monofilament fiber with high strength made of polypropylene. As a key additive in concrete and mortar, PP fiber could effectively control microcracks caused by solid-plastic shrinkage, dry shrinkage, and temperature changes, preventing and inhibiting the formation and development of cracks. This fiber could greatly improve the resistance to cracking and shock.

6 Basic Functions of NOVASTAR Polypropylene Fiber

Improved Crack Resistance

Compared with ordinary mortar or concrete, the crack resistance of those with 0.1% NOVASTAR monofilament fibers is increased by 70%.

Better Corrosion Resistance

Being synthetic, NOVASTAR PP fibers are immune to corrosion. It could maintain the integrity of the edges, corners, and surfaces of the product so that the steel bars in the concrete are not corroded.

Increased Resistance to Shock and Abrasion

PP fiber could absorb impact energy to reduce cracks. It enhances the continuity of medium materials and reduces the local stress concentration caused by the blocking of shock waves.Compared with ordinary mortar or concrete, the crack resistance of those with 0.1% NOVASTAR monofilament fibers is increased by 70%.

Enhanced Anti-freezing Capability

Adding polypropylene fibers to concrete can alleviate the internal stress of concrete caused by temperature changes and prevent the expansion of temperature cracks.Compared with ordinary mortar or concrete, the crack resistance of those with 0.1% NOVASTAR monofilament fibers is increased by 70%.

Enhanced Durability

As a secondary reinforcement material in mortar and concrete, Polypropylene Fiber is used to enhance surface durability by improving resistance to wear and erosion.

Improved Flexural Strength

PP Fiber could boost residual flexural strength (per ASTM C1609) by up to 30–50% (depending on dosage/fiber type), which is beneficial for slabs, pavements, and overlays.Compared with ordinary mortar or concrete, the crack resistance of those with 0.1% NOVASTAR monofilament fibers is increased by 70%.

4 Featured Applications of NOVASTAR Polypropylene Fiber

Precast Concrete

NOVASTAR PP fibers disperse tensile stresses during early curing, which is critical in high-speed precast production. It mitigates differential cooling cracks in steam-cured or large-section elements, such as beams and panels. It also prevents micro-cracks from propagating during demolding, transport, and installation.

Shotcrete and Tunnel Linings

Sprayed shotcrete applications often suffer from rapid moisture loss and thus early-age cracking. Adding PP fiber could effectively solve this problem. Also, NOVASTAR PP fibers enhance cohesion, improve adhesion to tunnel walls, and reduce material waste during spraying. PP Fiber also acts as a micro-reinforcement to handle ground movement and load shifts in tunnel linings.

Repair Mortar

PP fiber could minimize plastic and drying shrinkage cracks by dispersing stress through its 3D network. It also absorbs energy to reduce micro-fractures under dynamic loads, such as traffic vibration in bridge repairs. Furthermore, NOVASTAR PP fiber could improve fatigue resistance in seismic repairs or moving substrates.

Wall Putty

The main role of NOVASTAR Polypropylene Fiber in wall putty is to prevent shrinkage cracks and reduce plastic shrinkage. It acts as a micro-reinforcement, distributing stress caused by drying shrinkage and thermal contraction during curing. By forming a 3D network within the putty matrix, PP fibers minimize early-stage cracking while the material is still plastic.
