1, Crack anti-seepage: PVA fiber distributed in the concrete (mortar), can prevent the occurrence and development of cracks effectively,
improve water impermeability.
Comparison of PVA Fiber and PA fiber
| Fiber Types | Fiber infiltration amount (g/m3) | Crack reduction rate,% |
| PA fiber | 900 | 43 |
| PVA fiber | 900 | 86 |
2, Anti-shock and earthquake:PVA Fiber cement absorb shock energy effectively, improve seismic capacity.

3, Antifreeze, anti-fatigue: the temperature difference caused by the link stress, improve the anti-freeze, anti-fatigue ability.
4, Anti-wear: to reduce the pavement and other concrete surface of the dust, peeling, weathering.
5, Increase the toughness: to improve the brittleness of concrete, improve the impact resistance, bending ability.
6, Reduce weight :PVA Fiber can improve the tensile strength of concrete (shear) strength, it can reduce the prefabricated parts or casting
body cross- sectional size, thereby reducing their weight.
