Hybrid PP twisted fiber , pp macro fiber
Polypropylene twisted fiber is a new type of organic synthetic fiber. The product has the advantages of corrosion resistance, dispersion resistance, construction resistance and no damage to mixing equipment. At the same time, it has the advantages of high fracture strength, good dispersion in concrete and strong binding force. It can improve the characteristics of low tensile strength, small ultimate elongation and brittleness of concrete, and make the concrete have excellent properties such as tensile strength, bending resistance, crack resistance, fatigue resistance and high toughness. It has been applied in water conservancy, construction, bridge and other engineering fields.

Function of twisted fiber products
1: Effectively reduce the risk of concrete cracks, improve the tensile strength, bending strength and flexural strength of concrete
2: When encountering earthquake and other bad natural disasters, it can reduce the damage
3: Reduce fatal defects in concrete and improve impermeability of concrete
4: Protect the steel bar from corrosion and improve the durability of concrete structure
5: Increase the abrasion resistance of concrete
6: No abrasion to mixing equipment
7: It can be used to prevent tire injury
