Xinrui-te Macro fibers are made of 100% virgin polypropylene. It has high breaking strength, good dispersion, and strong binding force. The embossed surface has better bite force with concrete to improve the shrinkage resistance and crack resistance. Adding synthetic fibers to concrete may increase tensile strength. It is an effective way to solve shrinkage cracks on the surface. Especially in cast-in-place, shotcrete, and precast applications, the macro fibers greatly minimized concrete cracks. Macro fibers can maximize mechanical bonding. And also dissolves low tensile strength, low ultimate elongation, and brittleness of concrete.

The raw material of Macro Synthetic Fiber is polypropylene. Its function is the same as steel fiber, and it has the chemical stability of polypropylene. Concrete macro fiber is more suitable for coastal defense projects and docks.
