Polypropylene fiber
Donghong-PP Fiber
Donghong Polypropylene fiber is a kind of organic fiber product specially designed for mortar and concrete.Polypropylene fiber is made of polypropylene particles by continuous hot extrusion processing. Due to destaticization and anti-ultraviolet treatment,it is well-proportioned disperse in mortar and last for a long time,thus can effectively increase the bonding stress of fiber and base materials,prevent/decrease/ delay the early plastic cracking in mortar and concrete.
