Micro Synthetic Fiber is a high-performance additive designed to enhance the durability, strength, and crack resistance of concrete. Made from high-quality synthetic polymers such as polypropylene, these fibers are extremely fine—often measuring less than 1 mm in length—and are uniformly dispersed throughout the concrete mix. As a result, micro synthetic fiber plays a vital role in controlling plastic shrinkage cracking, minimizing bleeding, and improving surface integrity in both industrial and residential concrete applications.
