Fiber-Reinforced Concrete: Types, Benefits & Applications
Concrete is one of the most widely used construction materials, but traditional concrete has a major weakness: it’s prone to cracking under stress. That’s
Polypropylene Fiber (PP Fiber) Manufacturer
Polypropylene Fiber is a strong, lightweight synthetic fiber widely used in construction to improve the performance of concrete and mortar. It acts as an effective reinforcement agent, helping to reduce cracking, improve impact resistance, and enhance overall durability. PP fiber provides long-lasting strength without affecting the workability of the mix.
Mikem is a trusted manufacturer with rich experience in producing high-quality polypropylene fiber for construction use. We offer reliable products with stable quality, fast delivery, and competitive pricing. Our team works closely with customers to provide tailored solutions and strong technical support, helping achieve better results in every project.

Top 5 Functions of Mikem Polypropylene Fiber
1. Crack Control: Polypropylene fiber helps reduce small cracks in concrete and mortar by distributing stress evenly throughout the mix, especially during drying and shrinkage.
2. Better Impact Resistance: It strengthens the concrete, making it more resistant to heavy traffic, vibrations, and surface damage over time.
3. Enhanced Durability: By reinforcing the mix, the PP fiber helps improve long-term performance, allowing structures to withstand weather changes and mechanical stress.
4. Improved Fire Resistance: The fibers create tiny channels that release steam during high heat, helping to prevent concrete from breaking or spalling in fires.
5. Easy Mixing and Application: PP fiber is easy to mix into concrete without changing its workability, making it a convenient solution for stronger construction.
6. Corrosion Resistance: Unlike steel fibers, PP fibers are immune to rust, ideal for water-retaining structures or corrosive environments.

Enhancing Concrete Performance with Polypropylene Fiber
Concrete Slabs and Flooring
Polypropylene fiber is commonly used in concrete floors and slabs to reduce surface cracking, improve toughness, and extend service life under heavy loads or traffic.
Precast Concrete Products
It enhances the strength and durability of precast items like pipes, blocks, and panels, helping them resist damage during handling and installation.
Plastering and Renders
When added to plaster or render mixes, the fiber improves bonding strength and minimizes cracking, resulting in smoother, longer-lasting finishes.
Shotcrete and Tunnel Linings
In tunnel construction and sprayed concrete (shotcrete), polypropylene fiber provides better crack control and improves fire resistance, making the structure safer and more stable.

Frequently Asked Questions
Polypropylene, steel, glass, and synthetic fibers are commonly added to concrete. These fibers improve crack resistance, durability, and impact strength. Among them, polypropylene fiber is popular for reducing shrinkage cracks and enhancing flexibility without affecting the mix’s workability. Each fiber type serves specific performance needs in concrete applications.
Yes, PP fiber is generally considered safe. It is a non-toxic, chemically stable plastic that does not leach harmful substances under normal use. In construction, it’s valued for being lightweight, durable, and resistant to moisture and chemicals. It’s also widely used in food packaging and medical products, further supporting its safety profile.
Yes, Mikem operates its own manufacturing plant in China. Having full control over production allows us to maintain high-quality standards, reduce costs, and ensure dependable delivery. Our factory’s location also provides easy access to premium raw materials and strong industry support.
