Polypropylene Synthetic Macro Fiber

Product Description

Michem Polypropylene Synthetic macro fiber is high quality polypropylene in large structure of fibers, Michem Polypropylene Synthetic macro fiber produced by special molding process and surface modification to increase toughness of concrete.Synthetic macrofibers can be thought of like steel fibers, but simply not made of steel. The physical characteristics of these fibers (length, tensile strength, diameter, etc.) are all different, when compared to traditional synthetic micros. 

We provide different lengths, sizes, and packaging according to customer requirements.
