PP Fiber

Product Description                                                                           

PP Fiber is produced mainly by virgin polypropylene and in some special technology to make bunchy fiber with high strength.

When the fiber is put into dry-mixed mortar or concrete, it will effectively control the solid plastic shrinkage,drying shrinkage,temperature changes and other factors caused micro-cracks,to prevent and suppress the formation and development of cracks,greatly improving crack resistance barrier properties,impact resistance and seismic capacity of mortar and concrete
