Polypropylene fiber is a chopped fiber made of polypropylene material added to masterbatch, blended, spun, stretched, and treated by special techniques such as antistatic and anti-ultraviolet. Polypropylene engineering fiber is a special fiber for concrete and mortar. Polypropylene engineering fiber can effectively control cracks caused by shrinkage, shrinkage and temperature changes of concrete and mortar, greatly improve anti-cracking and anti-seepage performance, anti-wear performance, increase concrete toughness, and thus improve service life.

Polypropylene fiber It is mainly suitable for:

1. Anti-cracking and anti-seepage mortar for industrial and civil buildings;

2. Basement and underground works with high requirements for crack resistance and seepage prevention, saltwater works such as seawall dams

3, various precast concrete products

4. Concrete such as highways, bridges, tunnels, and airport runways;

5. Chemical plants with high requirements for alkali resistance and chemical corrosion.
