Polypropylene Fiber

as the new type concrete-strengthening fiber, it becomes a new popular subject in the field of fiber concrete research .

   With polypropylene as its raw material, this fiber is 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.

  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.
