In the field of modern materials, polypropylene fiber (PP fiber) has attracted much attention due to its unique properties and extensive applications. So, what exactly is polypropylene fiber?

Polypropylene fiber, abbreviated as PP fiber, is a synthetic fiber processed from polypropylene as the raw material through special techniques. Polypropylene is a thermoplastic resin with good chemical stability, heat resistance, and mechanical properties.

I. Appearance Characteristics

Visually, PP fiber usually appears as white or light yellow filaments. Its diameter generally ranges from a few micrometers to dozens of micrometers, and its length can be adjusted according to needs. PP fiber is lightweight, has a soft hand feel, and possesses good flexibility and processability.

II. Performance Features

(1) Chemical Corrosion Resistance

PP fiber exhibits excellent tolerance to a variety of chemical substances, including acids and alkalis. In environments with various chemical substances such as acids, alkalis, and salts, PP fiber can maintain stable performance and is not easily corroded or damaged. This enables it to have wide applications in some harsh chemical environments, such as in the chemical industry, sewage treatment, and other fields.

(2) Heat Resistance

PP fiber has good heat resistance. It can maintain stable performance at relatively high temperatures without being deformed or melted. This characteristic makes the application of PP fiber in some high-temperature environments possible, such as in automotive interiors, high-temperature filter materials, etc.

(3) Relatively High Strength

Furthermore, PP fiber has relatively high strength. Although its strength is not as high as that of some high-performance fibers, among ordinary synthetic fibers, the strength of PP fiber is quite prominent. It can withstand certain tensile and compressive forces and is suitable for various application scenarios that require a certain level of strength.

(4) Other Characteristics

In addition, PP fiber also has characteristics such as low moisture absorption and good wear resistance. It is not prone to absorbing moisture and can maintain a dry state, which is very beneficial for some applications that require moisture-proofing. Meanwhile, during the use process, PP fiber is not easily worn out and can maintain a relatively long service life.
