Polypropylene Monofilament Fiber

Multifunctional crack-resistant reinforcement material for coating and concrete applications

Monofilament PP Fiber manufacturer

Fiberego PP Fiber is specially designed as a microfiber concrete reinforcement material to prevent early plastic shrinkage cracks, improve tensile strength, and enhance the long-term durability of concrete and mortar.

Depending on the length, it is widely used in coatings, inks, artistic building materials, and industrial and civil concrete as an important functional additive for crack resistance, toughening and reinforcement modification.

Fiberego is a world leading concrete fiber distributor and supplier. FibeRego™ fibers are produced in strict accordance with the requirements of the B/T19001-2016/ISO9001:2015.
It can pass the American ASTM, CABO, ICBO, UL, and other relevant tests.

High-Performance Microfiber

Polypropylene Monofilament Fiber is a high-strength polypropylene material made by a special extrusion process.

Monofilament PP Microfiber features a tensile strength of over 500 MPa and a diameter of 30-32μm.

It boasts an elastic modulus of at least 3500 MPa and an elongation rate of 20-25%.

Furthermore, it is highly resistant to chemical degradation and operates optimally within a melting point range of 160 to 170°C.

Key Advantages of Fiberego PP Micro Fiber

Why Choose Polypropylene Microfiber for Concrete Reinforcement?

Our polypropylene fibers for concrete ensure:

Crack width control in the plastic and hardening phases.
Enhanced water resistance and reduced permeability.
Increased post-crack energy absorption.
Enhanced impact and abrasion resistance.
Improved load transfer in harsh environments.

These benefits make PP microfibers the best anti-crack additive for highways, tunnels, dams, industrial floors, precast concrete and shotcrete.
