Polypropylene Fiber (PP)

Polypropylene fiber is made of 100% pure polypropylene, after special production process and surface treatment technology. It ensures excellent dispersion and bonding with cement matrix in concrete and good aging resistance. It can be guaranteed to be effective in concrete for a long time. Polypropylene fibers are chemically stable in concrete and have good affinity with concrete materials. The fibers are uniformly dispersed in the concrete, forming an anchoring effect, which can instantly absorb a certain amount of destructive energy.

Advantages

1、Crack resistance:

The addition of polypropylene fiber improves cracks caused by plastic shrinkage, temperature stress, dry shrinkage and other factors, and the crack resistance is increased by more than 95% at a volume dosage of 0.1%.

2、 Anti-permeability:

Improve the anti-permeability and moisture-proof performance, and the anti-permeability ability is increased by more than 90% at 0.1% volume dosage.

3、 Impact resistance:

Improve the impact resistance and earthquake resistance. In the hammer test with 0.05% volume dosage, the number of initial cracking and crushing hammer blows was doubled.

4、 Anti-abrasion:

Improve the anti-abrasion ability by 50-100%, and reduce damage such as dusting, scaling, and flaking.

5、 Freeze-thaw resistance:

After 25 freeze-thaw cycles, no delamination and no decrease in compressive strength

6、 Improved fire resistance:

The fire resistance of mortar concrete added with fibers is improved; when the temperature is higher than 165°C, the fibers begin to melt. When the temperature continues to rise, the polypropylene evaporates and escapes, leaving a volume equivalent to the fiber in the concrete. hole.

7、 Cost saving:

Compared with traditional steel bars, imitation steel fibers can reduce construction costs to a certain extent, and at the same time reduce maintenance and replacement costs of steel bars.

Application

1. Concrete reinforcement:

Polypropylene fiber can be used in concrete as a reinforcement material, which can effectively improve the tensile strength, crack resistance and durability of concrete, and prevent concrete from cracking and breaking.

2. Waterproof isolation layer:

Polypropylene fiber can be used to make waterproof isolation layer, which can effectively prevent water penetration and damage, and protect the structure and internal facilities of buildings.

3. Wall insulation material:

Polypropylene fiber can be used to make wall insulation material, which can effectively improve the insulation performance of buildings, save energy and reduce energy consumption.

4. Ground materials:

Polypropylene fibers can be used to make ground materials, such as carpets, floors, anti-slip mats, etc., which can provide good anti-slip performance and durability, and protect the ground from damage.

5. Roof waterproof material:

Polypropylene fibers can be used to make roof waterproof materials, which can effectively prevent water penetration and damage, and protect the structure and internal facilities of buildings.

Features

1. Easy to use

It can be used without changing the mortar ratio, just put the fiber into the mortar mixture and stir evenly

2. Increase the bonding strength

Due to the large fiber fineness and uniform distribution in the mortar, it helps to hang the ash and increase the bonding strength between the plastering surface and the substrate

3. Strict selection of materials

It is easy to disperse in mortar or concrete and is not easy to agglomerate, which can make its anti-cracking performance play a good role and improve the impermeability of cement concrete

4. Stable performance

The chemical properties of the fibers are stable, and can be used in mortar and concrete prefabricated components to increase their performance
