With polypropylene as its raw material, fiber-mesh is produced by special technology.It appears net-like structure with many monofilaments connected.
The horizontal structure in monofilament can be destroyed in the course of the stirring owng to friction and rubbing, and the monofilament or net-like structure will fully stretch, thus the concrete is reinforce by a great number(more than 7 million pieces per cubic meter) of polypropylene fibers.
Features:
1.Prolong endurance
2.Improve steel protection
3.Increase cracking resistance
4.Increase fire resistance
5.Strong acid & alkali resistance and good endurance
6. Improve tensile, bending & folding strength
7. Increase seepage resistance
