What are the main advantages of polypropylene industrial filament?

Polypropylene industrial filament (i.e., polypropylene industrial long filament) has the following key advantages:

1. Lightweight: Polypropylene fiber is the lightest among all common synthetic fibers, with a density of approximately 0.90–0.91 g/cm³—lighter than water (which has a density of 1 g/cm³). As a result, products made from polypropylene fiber are lightweight, making them easy to transport and install. This makes it particularly well-suited for applications where weight is a critical factor, such as geotextiles, fishing nets, and floating ropes.

2. Excellent chemical corrosion resistance: It exhibits strong stability against chemicals such as acids, bases, and organic solvents, and is resistant to corrosion in most industrial and natural environments. It is suitable for corrosive environments including chemical processing, wastewater treatment, and marine applications.

3. Non-absorbent: Polypropylene fiber is virtually non-hygroscopic (with a moisture regain rate close to 0%). Even in humid or underwater environments, its strength and dimensional stability remain unchanged, making it ideal for long-term use in applications such as hydraulic engineering, filtration, and offshore operations.

4. Low cost: The raw material, polypropylene, is widely available, and its production process is relatively simple with low energy consumption. As a result, its price is more competitive than that of industrial fibers such as polyester and nylon, making it well-suited for large-scale industrial applications.

5. Non-toxic and odorless, with excellent hygiene: Complies with food contact and medical & healthcare-related standards, making it suitable for use in high-safety-demand applications such as food packaging, drinking water filtration, and medical non-woven fabrics.

6. Good abrasion resistance and tensile strength: After high-degree stretching and orientation, polypropylene industrial filaments exhibit high tensile strength (typically ranging from 5.5 to 7.0 g/d), meeting the mechanical requirements of most industrial applications.

7. Functional modification: By adding masterbatches or additives, the material can be endowed with functions such as UV resistance, flame retardancy, antistatic properties, anti-aging performance, and coloration, thereby expanding its applicability in various environments.

These advantages have made polypropylene industrial yarn widely used in various industrial fields, including geotextiles, seat belts, lifting slings, filtration materials, ropes and cables, woven bags, carpet backing fabrics, and fishing nets.
