Polypropylene Fiber (Monofilament)

Monofilament Polypropylene Fiber Manufacturer

Monofilament Polypropylene Fiber (PP Fiber) is a durable, lightweight synthetic fiber used to improve the quality and strength of concrete and mortar. It serves as a micro-reinforcement material that effectively minimizes shrinkage cracks, boosts resistance to impact, and enhances the durability of structures without compromising the mix’s workability.

At Mikem, we specialize in producing high-quality Monofilament Polypropylene Fiber designed for demanding construction environments. As a trusted manufacturer, we offer consistent product performance, fast lead times, and excellent technical support to help your projects run smoothly from start to finish.

Key Benefits of Monofilament Polypropylene Fiber

1. Shrinkage Crack Reduction: Distributes internal stresses more evenly in the mix, helping to reduce plastic shrinkage and hairline cracking during the early curing stage.

2. Increased Impact Resistance: Adds toughness to the concrete, making it more resilient to shocks, vibrations, and surface abrasion, especially in high-traffic areas.

3. Excellent Chemical and Corrosion Resistance: Unlike steel fibers, PP fibers are non-corrosive, making them ideal for sewage systems, water tanks, and marine structures.

4. Easy to Mix and Apply: Monofilament PP fibers disperse easily in concrete and mortar with no clumping, ensuring uniform performance across every batch.
