New Product Notice: Polypropylene Fibre (PP)—Mesh/ Fibrillated packed in 600g/ water soluble paper bag is ready for export !


Frillated fiber with polypropylene as its raw material, this fiber was produced by special technology. The products appear net-like structure with many fiber monofilaments connected. When the fiber is put into the concrete, the horizontal structure in fiber monofilament can be destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net-like structure will fully stretch, thus the concrete is reinforced by a great number of polypropylene fibers.

Typical physical properties:

As a new type concrete-strengthening fiber, it becomes a new popular subject in the field of fiber concrete research and application after glass fiber and steel fiber. The reinforced functions run as follows: Increase seepage resistance:Prolong endurance/ Improve steel protection

  1. Increase cracking resistance: Increase fire resistance/Strengthen spurt & fatigue
  2. Improve tensile, bending & folding strength: Improve plastic deformity
  3. Strong acid & alkali resistance and good endurance


1. Projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance. The life span of these projects will be lengthened for 5-10 years.

2. The walls of tunnels, mines, roofs and reservoir projects with special construction. When using spray technology in concrete construction, the polypropylene fiber added into the concrete can effectively decrease the spray concrete's deformation rate of the walls less than 8% and that of the roof less than 12%, and also can reduce the friction. It can improve the constructing efficiency and working environment and popularize the spray technology.

3. River courses and dams, etc. The polypropylene fiber can improve concrete's resistance to crack and squirt andto lengthen projects' life span.

4. Military defense works, dock banks and piers, etc. This fiber can greatly strengthen the concrete's spurt resistance and heighten these projects' safety and lengthen their life span.
