China's leading manufacturer of reinforced polypropylene fibers, offering comprehensive fiber solutions.
Polypropylene Fibrillated Fiber is a high-performance synthetic reinforcement material designed for concrete, mortar, shotcrete, and cement-based products.
Its fibrillated mesh structure improves bonding within the matrix, helping reduce shrinkage cracking, increase toughness, and enhance long-term durability.
At Michem, we supply stable-quality PP fibrillated fiber with customizable dimensions, reliable bulk delivery, and technical support for different construction applications.
Polypropylene fibrillated fiber is produced from polypropylene film that is slit and fibrillated into a net-like structure. During mixing, fibers disperse in concrete and form a 3D reinforcement network, improving crack resistance and overall performance.
Michem is committed to continuous innovation and providing high-quality pp fiber solutions for concrete. The following is a summary of product details:

Standard plastic bags (12 mm or thicker): LCL container capacity: 10 tons; High-cube container: 24 tons .
Standard plastic bags (thinner than 9 mm): LCL container capacity: 9 tons; High-cube container: 22.4 tons (560 kg/pallet, 40 pallets total).
It is used to reinforce concrete and mortar, reduce cracking, and improve toughness and durability.
Monofilament fiber is single-strand, while fibrillated fiber has a mesh-like structure that can provide stronger mechanical anchorage in cement-based systems.
In some non-structural crack-control applications, it can reduce dependence on steel mesh. Final reinforcement decisions should follow engineering design codes.
Typical dosage is 0.6–2.0 kg/m³, depending on your mix design and target performance.
