Short PP Fiber

Polypropylene Fiber-PP Fiber

Polypropylene Fiber (PP Fiber) with polypropylene as its raw material, this fiber is produced by special technology. The products have net-like structure with many fiber monofilaments.

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.

General Properties

- Increase seepage resistance

- Prolong endurance

- Improve steel protection

- Increase cracking resistance

- Increase fire resistance
