The diameter of PP microfiber is smaller, the diameter is generally no more than 50 μ m, and the length is generally no more than 20 mm. It is made by melting isotactic polypropylene and drawing directly through several spinneret holes. The cross section of the pp microfiber is round or shaped. Several monofilaments are stretched, shaped and cut to a certain length to form a fiber bundle. The PP microfiber bundle can be separated into monofilament during mixing with concrete.

Properties of PP microfiber
1. High strength and modulus of elasticity are conducive to the mechanical properties of concrete.
2. It has a strong grip with the cement surface, and hydrophilic treatment is conducive to ash hanging and strength improvement.
Polypropylene fiber
3. It has good dispersibility and no agglomeration, which effectively guarantees its crack resistance.
4. The chemical properties of the fiber are stable, acid and alkali resistant.
Application of the pp microfiber
1. Concrete rigid self waterproof structure, basement floor, side wall, roof, roof slab, pool, etc;
2. Cement mortar, dry mortar, thermal insulation mortar, crack resistant mortar, internal and external wall plastering mortar, etc;
3. Crack resistance, impact resistance, wear resistance, earthquake resistance and other requirements;
4. Bridge deck, pier, port and wharf, water conservancy engineering, etc.
Packing
The pp microfiber can be packing as the requirements from the cutomers.
Normal packing :1kg/small bag,20kg/woven bag
