What are the advantages and disadvantages of polypropylene fiber?

In many modern construction projects, in order to improve the performance of concrete, many construction parties will add some new building materials - polypropylene fibers. After countless practical tests, it has been proven that polypropylene fibers can indeed improve the performance of concrete. In order to better utilize polypropylene fibers, it is important to understand their advantages and disadvantages. This article focuses on introducing this aspect to you.

Advantages of polypropylene fiber:

1. Polypropylene fiber has the advantage of being lightweight, and its quality is superior to that of cotton.

2. Polypropylene fibers have the advantage of zero moisture absorption, and their non hygroscopicity can maintain the stability of the internal structure of concrete.

3. Polypropylene fibers have the advantages of high wear resistance and strength.

4. Polypropylene fibers have the advantage of good corrosion resistance and can withstand weak acids and bases.

5. Polypropylene fibers have the advantage of good stability, such as being easy to clean when exposed to organic solvents.

Disadvantages of polypropylene fiber:

1. The disadvantages of polypropylene fiber include poor dyeing performance, light color, low color fastness, and ordinary dyes cannot dye it.

2. Polypropylene fiber has poor moisture absorption, which can be considered one of the worst among chemical fibers, and is not conducive to water vapor dispersion in certain usage scenarios.

3. The heat resistance and aging resistance of polypropylene fibers are poor. Its raw material is propylene, which has a low melting point and poor stability under heat, light, and other influences, resulting in poor aging and heat resistance.
