1.5mm Polypropylene PP fiber Synthetic Short micro fiber

 1.5mm Polypropylene PP fiber  Synthetic Short micro fiber is made by 100% virgin polypropylene,adopting unique manufacturing process to make high strength bundle monofilament fiber. when the fiber is put into the concrete,concrete (or mortar) can effectively control concrete (or mortar) micro-cracks which is caused by plastic shrinkage, temperature changes and other factors, to prevent and inhibit the formation and development of cracks, greatly improved crack resistance of concrete, impact resistance and seismic capacity. The 1.5mm PP fiber is also used for  paper ,nonwen bag, oil well, and other projects .
