Engineering fiber
Polypropylene fiber
Application- it is widely used in road, protection railings, bridge constructions, building of water diversion facilities in hydroelectric project, of flank wall and floor of basements and civil architecture. It has sound effect of anti-crack & anti-leakage when mixed in concrete and mortar.
Features- Polypropylene fiber is high-performance fiber which is widely used in concrete and mortar project, because it can effectively control the micro crack in result of plastic shrinkage, air shrinkage, temperature variation, and prevent the crack from widening. It can prolong the life of concrete by improving its nature of resistance to erosion and abrasion.

Polyester fiber
Application- widely used in bituminous pavement and bridge construction, cold-patch and cementation of fissures of the road to protect the project from cracking.
Features- it is heat-resistant in spite of features of good fineness, high-strength, easy to scatter, can be widely used in the project of bitulith to improve the nature of resistance to erosion and abrasion of the concrete.

Polyacrylonitrile fiber
Application- widely used in bituminous pavement and bridge construction, cold-patch and cementation of fissures of the road to protect the project from cracking.
Features-
1. enhance the crack resistance of cement concrete effectively-
a) the good cohesiveness with concrete makes it have bearing use for the architecture, and prevent the appearance of crack.
b) Avoid desiccation fissure by adjusting moisture content.
c) Reduce fissures by adjusting heat-release or other temperature change.
2. Improve anti-permeability and freezing resistance of concrete, increase its durability.
a) The fiber can highly reduce the size and quantity of pore in the concrete, and improves the anti-permeability and freezing resistance of concrete. The frequency of freezing resistance of concrete is up to 600 times.
3. Lower the brittleness of concrete and prevent the crack from widening.
4. Improve the stability of concrete under high temperature.
5. Improve the tensile strength, shear strength and crack resistance under low temperature.
6. Improve the antifatigue and durability of concrete.
7. Improve the moisture stability and toughness of concrete.
8. Improve the abrasive resistance and anti-strip feature of the concrete.
