High-Strength Polypropylene Synthetic Macro Fibers
High-strength synthetic macro fibers for concrete have high tensile strength and elastic modulus, which can improve the impact resistance of precast concrete components. With 40,000 fibers per cubic meter of concrete arranged in a three-dimensional structure, these fibers provide overall reinforcement, ensuring worry-free post-installation activities
Description
High-strength synthetic macro fibers are made from 100% polypropylene raw materials using our unique drawing process. The product has a tensile strength of over 650 MPa and an elastic modulus of over 10 GPa. It is mainly used in tunnel segments, high-strength concrete pipe piles, square piles, ballastless track slabs, embedded track slabs, floating slabs, stadium precast seats, precast concrete boxes, and almost all precast concrete components. Domestically, we are the first company to produce high-strength synthetic macro fibers with a tensile strength exceeding 650 MPa. As a result, we are partners with China State Construction Engineering Corporation, China Railway Construction Corporation, Shanghai Tunnel Engineering Co., Ltd., and China Communications Construction Company in the field of high-strength precast concrete components. We have participated in over 200 various engineering projects, accumulating tens of thousands of hours of production experience with high-strength synthetic macro fibers. We have established a standardized production model to ensure consistent quality in every batch, rather than relying on the production experience of individual technicians. Serving global customers well is our next goal.

User guidance
Dosage: The general dosage is 3.0-8.0kg/m3.
Length: The length should be 35-58mm. Dependent on precast concrete elements.
Mixing: It is advisable to add fibers in the concrete mixing station to ensure that the fibers are evenly dispersed.
Curing: The curing process after adding fibers is exactly the same as the system without adding fibers.
