China's leading manufacturer of reinforced polypropylene fibers, offering comprehensive fiber solutions.
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.
