Reliable Polypropylene Synthetic Microfiber Supplier for Concrete & Mortar
China's leading manufacturer of reinforced polypropylene fibers, offering comprehensive fiber solutions.
HIGH QUALITY MICRO SYNTHETIC FIBERS
A long-established Synthetic fiber factory from Tai'an, China
Michem Polypropylene synthetic microfiber is a high-strength fiber made of 100% virgin polypropylene as the raw material. The fibers are extremely fine, single filaments, specifically designed to help mitigate the formation of plastic shrinkage cracking in concrete.
Polypropylene synthetic microfiber is a high-performance anti-crack reinforcement additive for concrete, mortar, and dry-mix applications. Michem provides stable-quality PP microfiber in multiple lengths and diameters to reduce plastic shrinkage cracking, improve toughness, and enhance long-term durability.
As a leading reinforced polypropylene fiber manufacturer in China,We utilize petrochemical polypropylene pellets as raw materials. TenaBrix producing fibers with exceptional quality and reliability. These fibers disperse evenly in concrete or mortar, significantly improving durability and performance.
Whether for industrial floors, precast elements, repair mortars or general concrete reinforcement, TenaBrix provides not only this microfiber but also a full range of fiber solutions to meet diverse construction needs.

Best-Selling Lengths & Applications of PP Micro Fiber
By choosing the right length, you can optimize crack resistance, toughness, and durability across a wide range of concrete projects.
6mm Polypropylene Fiber
6mm PP fibers are commonly used in thin-layer mortars to improve crack resistance and prevent microcracks caused by temperature fluctuations, shrinkage, and other stress factors. Their shorter length allows for uniform dispersion within the mortar matrix, effectively controlling crack propagation.
12mm Polypropylene Fiber
12mm PP fibers are designed for thicker concrete structures, especially in load-bearing areas or zones with high stress concentration. The longer fibers enhance impact resistance, flexural strength, and crack control, significantly improving the structural performance of concrete.
18mm Polypropylene Fiber
18mm PP fibers are specially designed for large-scale and heavy-duty concrete projects. With their extended length, they provide superior toughness, energy absorption, and crack bridging performance, making them ideal for structures exposed to dynamic loads and harsh environments.
